worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Internal
This directory contains internal code for cloud.google.com/go packages.
## .repo-metadata-full.json
`.repo-metadata-full.json` contains metadata about the packages in this repo. It
is generated by `internal/gapicgen/generator`. It's processed by external tools
to build lists of all of the packages.
Don't make breaking changes to the format without consulting with the external
tools.
One day, we may want to create individual `.repo-metadata.json` files next to
each package, which is the pattern followed by some other languages. External
tools would then talk to pkg.go.dev or some other service to get the overall
list of packages and use the `.repo-metadata.json` files to get the additional
metadata required. For now, `.repo-metadata-full.json` includes everything.
## cloudbuild.yaml
To kick off a build locally run from the repo root:
```bash
gcloud builds submit --project=cloud-devrel-kokoro-resources --config=internal/cloudbuild.yaml
```
### Updating OwlBot SHA
You may want to manually update the which version of the post processor will be
used -- to do this you need to update the SHA in the OwlBot lock file. Start by
running the following commands:
```bash
docker pull gcr.io/cloud-devrel-public-resources/owlbot-go:latest
docker inspect --format='{{index .RepoDigests 0}}' gcr.io/cloud-devrel-public-resources/owlbot-go:latest
```
This will give you a SHA. You can use this value to update the value in
`.github/.OwlBot.lock.yaml`.
*Note*: OwlBot will eventually open a pull request to update this value if it
discovers a new version of the container.

* This release contains changes to fully align this library's retry strategy
with best practices as described in the
Cloud Storage [docs](https://cloud.google.com/storage/docs/retry-strategy).
* The library will now retry only idempotent operations by default. This means
that for certain operations, including object upload, compose, rewrite,
update, and delete, requests will not be retried by default unless
[idempotency conditions](https://cloud.google.com/storage/docs/retry-strategy#idempotency)
for the request have been met.
* The library now has methods to configure aspects of retry policy for
API calls, including which errors are retried, the timing of the
exponential backoff, and how idempotency is taken into account.
* If you wish to re-enable retries for a non-idempotent request, use the
[RetryAlways](https://pkg.go.dev/cloud.google.com/go/storage@main#RetryAlways)
policy.
* For full details on how to configure retries, see the
[package docs](https://pkg.go.dev/cloud.google.com/go/storage@main#hdr-Retrying_failed_requests)
and the
[Cloud Storage docs](https://cloud.google.com/storage/docs/retry-strategy)

## Cloud Storage [![Go Reference](https://pkg.go.dev/badge/cloud.google.com/go/storage.svg)](https://pkg.go.dev/cloud.google.com/go/storage)
- [About Cloud Storage](https://cloud.google.com/storage/)
- [API documentation](https://cloud.google.com/storage/docs)
- [Go client documentation](https://cloud.google.com/go/docs/reference/cloud.google.com/go/storage/latest)
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/main/storage)
### Example Usage
First create a `storage.Client` to use throughout your application:
[snip]:# (storage-1)
```go
client, err := storage.NewClient(ctx)
if err != nil {
log.Fatal(err)
}
```
[snip]:# (storage-2)
```go
// Read the object1 from bucket.
rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
if err != nil {
log.Fatal(err)
}
defer rc.Close()
body, err := io.ReadAll(rc)
if err != nil {
log.Fatal(err)
}
```

Package storage provides an easy way to work with Google Cloud Storage.
Google Cloud Storage stores data in named objects, which are grouped into buckets.
More information about Google Cloud Storage is available at
https://cloud.google.com/storage/docs.
See https://pkg.go.dev/cloud.google.com/go for authentication, timeouts,
connection pooling and similar aspects of this package.
# Creating a Client
To start working with this package, create a [Client]:
ctx := context.Background()
client, err := storage.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
The client will use your default application credentials. Clients should be
reused instead of created as needed. The methods of [Client] are safe for
concurrent use by multiple goroutines.
You may configure the client by passing in options from the [google.golang.org/api/option]
package. You may also use options defined in this package, such as [WithJSONReads].
If you only wish to access public data, you can create
an unauthenticated client with
client, err := storage.NewClient(ctx, option.WithoutAuthentication())
To use an emulator with this library, you can set the STORAGE_EMULATOR_HOST
environment variable to the address at which your emulator is running. This will
send requests to that address instead of to Cloud Storage. You can then create
and use a client as usual:
// Set STORAGE_EMULATOR_HOST environment variable.
err := os.Setenv("STORAGE_EMULATOR_HOST", "localhost:9000")
if err != nil {
// TODO: Handle error.
}
// Create client as usual.
client, err := storage.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
// This request is now directed to http://localhost:9000/storage/v1/b
// instead of https://storage.googleapis.com/storage/v1/b
if err := client.Bucket("my-bucket").Create(ctx, projectID, nil); err != nil {
// TODO: Handle error.
}
Please note that there is no official emulator for Cloud Storage.
# Buckets
A Google Cloud Storage bucket is a collection of objects. To work with a
bucket, make a bucket handle:
bkt := client.Bucket(bucketName)
A handle is a reference to a bucket. You can have a handle even if the
bucket doesn't exist yet. To create a bucket in Google Cloud Storage,
call [BucketHandle.Create]:
if err := bkt.Create(ctx, projectID, nil); err != nil {
// TODO: Handle error.
}
Note that although buckets are associated with projects, bucket names are
global across all projects.
Each bucket has associated metadata, represented in this package by
[BucketAttrs]. The third argument to [BucketHandle.Create] allows you to set
the initial [BucketAttrs] of a bucket. To retrieve a bucket's attributes, use
[BucketHandle.Attrs]:
attrs, err := bkt.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("bucket %s, created at %s, is located in %s with storage class %s\n",
attrs.Name, attrs.Created, attrs.Location, attrs.StorageClass)
# Objects
An object holds arbitrary data as a sequence of bytes, like a file. You
refer to objects using a handle, just as with buckets, but unlike buckets
you don't explicitly create an object. Instead, the first time you write
to an object it will be created. You can use the standard Go [io.Reader]
and [io.Writer] interfaces to read and write object data:
obj := bkt.Object("data")
// Write something to obj.
// w implements io.Writer.
w := obj.NewWriter(ctx)
// Write some text to obj. This will either create the object or overwrite whatever is there already.
if _, err := fmt.Fprintf(w, "This object contains text.\n"); err != nil {
// TODO: Handle error.
}
// Close, just like writing a file.
if err := w.Close(); err != nil {
// TODO: Handle error.
}
// Read it back.
r, err := obj.NewReader(ctx)
if err != nil {
// TODO: Handle error.
}
defer r.Close()
if _, err := io.Copy(os.Stdout, r); err != nil {
// TODO: Handle error.
}
// Prints "This object contains text."
Objects also have attributes, which you can fetch with [ObjectHandle.Attrs]:
objAttrs, err := obj.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("object %s has size %d and can be read using %s\n",
objAttrs.Name, objAttrs.Size, objAttrs.MediaLink)
# Listing objects
Listing objects in a bucket is done with the [BucketHandle.Objects] method:
query := &storage.Query{Prefix: ""}
var names []string
it := bkt.Objects(ctx, query)
for {
attrs, err := it.Next()
if err == iterator.Done {
break
}
if err != nil {
log.Fatal(err)
}
names = append(names, attrs.Name)
}
Objects are listed lexicographically by name. To filter objects
lexicographically, [Query.StartOffset] and/or [Query.EndOffset] can be used:
query := &storage.Query{
Prefix: "",
StartOffset: "bar/", // Only list objects lexicographically >= "bar/"
EndOffset: "foo/", // Only list objects lexicographically < "foo/"
}
// ... as before
If only a subset of object attributes is needed when listing, specifying this
subset using [Query.SetAttrSelection] may speed up the listing process:
query := &storage.Query{Prefix: ""}
query.SetAttrSelection([]string{"Name"})
// ... as before
# ACLs
Both objects and buckets have ACLs (Access Control Lists). An ACL is a list of
ACLRules, each of which specifies the role of a user, group or project. ACLs
are suitable for fine-grained control, but you may prefer using IAM to control
access at the project level (see [Cloud Storage IAM docs].
To list the ACLs of a bucket or object, obtain an [ACLHandle] and call [ACLHandle.List]:
acls, err := obj.ACL().List(ctx)
if err != nil {
// TODO: Handle error.
}
for _, rule := range acls {
fmt.Printf("%s has role %s\n", rule.Entity, rule.Role)
}
You can also set and delete ACLs.
# Conditions
Every object has a generation and a metageneration. The generation changes
whenever the content changes, and the metageneration changes whenever the
metadata changes. [Conditions] let you check these values before an operation;
the operation only executes if the conditions match. You can use conditions to
prevent race conditions in read-modify-write operations.
For example, say you've read an object's metadata into objAttrs. Now
you want to write to that object, but only if its contents haven't changed
since you read it. Here is how to express that:
w = obj.If(storage.Conditions{GenerationMatch: objAttrs.Generation}).NewWriter(ctx)
// Proceed with writing as above.
# Signed URLs
You can obtain a URL that lets anyone read or write an object for a limited time.
Signing a URL requires credentials authorized to sign a URL. To use the same
authentication that was used when instantiating the Storage client, use
[BucketHandle.SignedURL].
url, err := client.Bucket(bucketName).SignedURL(objectName, opts)
if err != nil {
// TODO: Handle error.
}
fmt.Println(url)
You can also sign a URL without creating a client. See the documentation of
[SignedURL] for details.
url, err := storage.SignedURL(bucketName, "shared-object", opts)
if err != nil {
// TODO: Handle error.
}
fmt.Println(url)
# Post Policy V4 Signed Request
A type of signed request that allows uploads through HTML forms directly to Cloud Storage with
temporary permission. Conditions can be applied to restrict how the HTML form is used and exercised
by a user.
For more information, please see the [XML POST Object docs] as well
as the documentation of [BucketHandle.GenerateSignedPostPolicyV4].
pv4, err := client.Bucket(bucketName).GenerateSignedPostPolicyV4(objectName, opts)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("URL: %s\nFields; %v\n", pv4.URL, pv4.Fields)
# Credential requirements for signing
If the GoogleAccessID and PrivateKey option fields are not provided, they will
be automatically detected by [BucketHandle.SignedURL] and
[BucketHandle.GenerateSignedPostPolicyV4] if any of the following are true:
- you are authenticated to the Storage Client with a service account's
downloaded private key, either directly in code or by setting the
GOOGLE_APPLICATION_CREDENTIALS environment variable (see [Other Environments]),
- your application is running on Google Compute Engine (GCE), or
- you are logged into [gcloud using application default credentials]
with [impersonation enabled].
Detecting GoogleAccessID may not be possible if you are authenticated using a
token source or using [option.WithHTTPClient]. In this case, you can provide a
service account email for GoogleAccessID and the client will attempt to sign
the URL or Post Policy using that service account.
To generate the signature, you must have:
- iam.serviceAccounts.signBlob permissions on the GoogleAccessID service
account, and
- the [IAM Service Account Credentials API] enabled (unless authenticating
with a downloaded private key).
# Errors
Errors returned by this client are often of the type [googleapi.Error].
These errors can be introspected for more information by using [errors.As]
with the richer [googleapi.Error] type. For example:
var e *googleapi.Error
if ok := errors.As(err, &e); ok {
if e.Code == 409 { ... }
}
# Retrying failed requests
Methods in this package may retry calls that fail with transient errors.
Retrying continues indefinitely unless the controlling context is canceled, the
client is closed, or a non-transient error is received. To stop retries from
continuing, use context timeouts or cancellation.
The retry strategy in this library follows best practices for Cloud Storage. By
default, operations are retried only if they are idempotent, and exponential
backoff with jitter is employed. In addition, errors are only retried if they
are defined as transient by the service. See the [Cloud Storage retry docs]
for more information.
Users can configure non-default retry behavior for a single library call (using
[BucketHandle.Retryer] and [ObjectHandle.Retryer]) or for all calls made by a
client (using [Client.SetRetry]). For example:
o := client.Bucket(bucket).Object(object).Retryer(
// Use WithBackoff to change the timing of the exponential backoff.
storage.WithBackoff(gax.Backoff{
Initial: 2 * time.Second,
}),
// Use WithPolicy to configure the idempotency policy. RetryAlways will
// retry the operation even if it is non-idempotent.
storage.WithPolicy(storage.RetryAlways),
)
// Use a context timeout to set an overall deadline on the call, including all
// potential retries.
ctx, cancel := context.WithTimeout(ctx, 5*time.Second)
defer cancel()
// Delete an object using the specified strategy and timeout.
if err := o.Delete(ctx); err != nil {
// Handle err.

// Package storage is an auto-generated package for the

//
// Lets you store and retrieve potentially-large, immutable data objects.
//
// NOTE: This package is in alpha. It is not stable, and is likely to change.
//
// # General documentation
//
// For information about setting deadlines, reusing contexts, and more
// please visit https://pkg.go.dev/cloud.google.com/go.
//
// # Example usage
//
// To get started with this package, create a client.
//
// ctx := context.Background()
// // This snippet has been automatically generated and should be regarded as a code template only.
// // It will require modifications to work:
// // - It may require correct/in-range values for request initialization.
// // - It may require specifying regional endpoints when creating the service client as shown in:
// // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
// c, err := storage.NewClient(ctx)
// if err != nil {
// // TODO: Handle error.
// }
// defer c.Close()
//
// The client will use your default application credentials. Clients should be reused instead of created as needed.
// The methods of Client are safe for concurrent use by multiple goroutines.
// The returned client must be Closed when it is done being used.
//
// # Using the Client
//
// The following is an example of making an API call with the newly created client.
//
// ctx := context.Background()
// // This snippet has been automatically generated and should be regarded as a code template only.

// # Use of Context
//
// The ctx passed to NewClient is used for authentication requests and

// Individual methods on the client use the ctx given to them.
//
// To close the open connection, use the Close() method.

// ChunkSize controls the maximum number of bytes of the object that the
// Writer will attempt to send to the server in a single request. Objects
// smaller than the size will be sent in a single request, while larger
// objects will be split over multiple requests. The value will be rounded up
// to the nearest multiple of 256K. The default ChunkSize is 16MiB.
//
// Each Writer will internally allocate a buffer of size ChunkSize. This is
// used to buffer input data and allow for the input to be sent again if a
// request must be retried.
//
// If you upload small objects (< 16MiB), you should set ChunkSize
// to a value slightly larger than the objects' sizes to avoid memory bloat.
// This is especially important if you are uploading many small objects

// https://cloud.google.com/storage/docs/json_api/v1/how-tos/upload#size
// for more information about performance trade-offs related to ChunkSize.
//
// If ChunkSize is set to zero, chunking will be disabled and the object will
// be uploaded in a single request without the use of a buffer. This will
// further reduce memory used during uploads, but will also prevent the writer
// from retrying in case of a transient error from the server or resuming an
// upload that fails midway through, since the buffer is required in order to
// retry the failed request.

// ChunkSize must be set before the first Write call.

//
// For uploads of larger files, the Writer will attempt to retry if the

// If a single chunk has been attempting to upload for longer than this
// deadline and the request fails, it will no longer be retried, and the error
// will be returned to the caller. This is only applicable for files which are
// large enough to require a multi-chunk resumable upload. The default value
// is 32s. Users may want to pick a longer deadline if they are using larger

// Package cmp determines equality of values.
//
// This package is intended to be a more powerful and safer alternative to
// reflect.DeepEqual for comparing whether two values are semantically equal.
// It is intended to only be used in tests, as performance is not a goal and
// it may panic if it cannot compare the values. Its propensity towards
// panicking means that its unsuitable for production environments where a
// spurious panic may be fatal.
//
// The primary features of cmp are:
//
// - When the default behavior of equality does not suit the test's needs,
// custom equality functions can override the equality operation.
// For example, an equality function may report floats as equal so long as
// they are within some tolerance of each other.
//
// - Types with an Equal method may use that method to determine equality.
// This allows package authors to determine the equality operation
// for the types that they define.
//
// - If no custom equality functions are used and no Equal method is defined,
// equality is determined by recursively comparing the primitive kinds on
// both values, much like reflect.DeepEqual. Unlike reflect.DeepEqual,
// unexported fields are not compared by default; they result in panics
// unless suppressed by using an Ignore option (see cmpopts.IgnoreUnexported)
// or explicitly compared using the Exporter option.

// TODO(≥go1.18): Use any instead of interface{}.
// Equal reports whether x and y are equal by recursively applying the
// following rules in the given order to x and y and all of their sub-values:
//
// - Let S be the set of all Ignore, Transformer, and Comparer options that
// remain after applying all path filters, value filters, and type filters.
// If at least one Ignore exists in S, then the comparison is ignored.
// If the number of Transformer and Comparer options in S is non-zero,
// then Equal panics because it is ambiguous which option to use.
// If S contains a single Transformer, then use that to transform
// the current values and recursively call Equal on the output values.
// If S contains a single Comparer, then use that to compare the current values.
// Otherwise, evaluation proceeds to the next rule.
//
// - If the values have an Equal method of the form "(T) Equal(T) bool" or
// "(T) Equal(I) bool" where T is assignable to I, then use the result of
// x.Equal(y) even if x or y is nil. Otherwise, no such method exists and
// evaluation proceeds to the next rule.
//
// - Lastly, try to compare x and y based on their basic kinds.
// Simple kinds like booleans, integers, floats, complex numbers, strings,
// and channels are compared using the equivalent of the == operator in Go.
// Functions are only equal if they are both nil, otherwise they are unequal.
//
// Structs are equal if recursively calling Equal on all fields report equal.
// If a struct contains unexported fields, Equal panics unless an Ignore option
// (e.g., cmpopts.IgnoreUnexported) ignores that field or the Exporter option
// explicitly permits comparing the unexported field.
//
// Slices are equal if they are both nil or both non-nil, where recursively
// calling Equal on all non-ignored slice or array elements report equal.
// Empty non-nil slices and nil slices are not equal; to equate empty slices,
// consider using cmpopts.EquateEmpty.
//
// Maps are equal if they are both nil or both non-nil, where recursively
// calling Equal on all non-ignored map entries report equal.
// Map keys are equal according to the == operator.
// To use custom comparisons for map keys, consider using cmpopts.SortMaps.
// Empty non-nil maps and nil maps are not equal; to equate empty maps,
// consider using cmpopts.EquateEmpty.
//
// Pointers and interfaces are equal if they are both nil or both non-nil,
// where they have the same underlying concrete type and recursively
// calling Equal on the underlying values reports equal.
//
// Before recursing into a pointer, slice element, or map, the current path
// is checked to detect whether the address has already been visited.
// If there is a cycle, then the pointed at values are considered equal
// only if both addresses were previously visited in the same path step.

// computing sub-optimal edit-scripts between two lists.

// The algorithm is approximately as follows:
// - Searching for differences switches back-and-forth between
// a search that starts at the beginning (the top-left corner), and
// a search that starts at the end (the bottom-right corner).
// The goal of the search is connect with the search
// from the opposite corner.
// - As we search, we build a path in a greedy manner,
// where the first match seen is added to the path (this is sub-optimal,
// but provides a decent result in practice). When matches are found,
// we try the next pair of symbols in the lists and follow all matches
// as far as possible.
// - When searching for matches, we search along a diagonal going through
// through the "frontier" point. If no matches are found,
// we advance the frontier towards the opposite corner.
// - This algorithm terminates when either the X coordinates or the
// Y coordinates of the forward and reverse frontier points ever intersect.
// This algorithm is correct even if searching only in the forward direction
// or in the reverse direction. We do both because it is commonly observed
// that two lists commonly differ because elements were added to the front
// or end of the other list.

# HTTP JSON Error Schema
The `error.proto` represents the HTTP-JSON schema used by Google APIs to convey
error payloads as described by https://cloud.google.com/apis/design/errors#http_mapping.
This package is for internal parsing logic only and should not be used in any
other context.
## Regeneration
To regenerate the protobuf Go code you will need the following:
* A local copy of [googleapis], the absolute path to which should be exported to
the environment variable `GOOGLEAPIS`
* The protobuf compiler [protoc]
* The Go [protobuf plugin]
* The [goimports] tool
From this directory run the following command:
```sh
protoc -I $GOOGLEAPIS -I. --go_out=. --go_opt=module=github.com/googleapis/gax-go/v2/apierror/internal/proto error.proto
goimports -w .
```
Note: the `module` plugin option ensures the generated code is placed in this
directory, and not in several nested directories defined by `go_package` option.
[googleapis]: https://github.com/googleapis/googleapis
[protoc]: https://github.com/protocolbuffers/protobuf#protocol-compiler-installation
[protobuf plugin]: https://developers.google.com/protocol-buffers/docs/reference/go-generated
