/*
Package client provides NeoFS API client implementation.
The main component is Client type. It is a virtual connection to the network
and provides methods for executing operations on the server.
Create client instance:
var c client.Client
Initialize client state:
var prm client.PrmInit
prm.SetDefaultPrivateKey(key)
// ...
c.Init(prm)
Connect to the NeoFS server:
var prm client.PrmDial
prm.SetServerURI("localhost:8080")
prm.SetDefaultPrivateKey(key)
// ...
err := c.Dial(prm)
// ...
Execute NeoFS operation on the server:
var prm client.PrmContainerPut
prm.SetContainer(cnr)
// ...
res, err := c.ContainerPut(context.Background(), prm)
err := c.Dial(dialPrm)
if err == nil {
err = apistatus.ErrFromStatus(res.Status())
}
// ...
Consume custom service of the server:
syntax = "proto3";
service CustomService {
rpc CustomRPC(CustomRPCRequest) returns (CustomRPCResponse);
}
import "github.com/nspcc-dev/neofs-api-go/v2/rpc/client"
import "github.com/nspcc-dev/neofs-api-go/v2/rpc/common"
req := new(CustomRPCRequest)
// ...
resp := new(CustomRPCResponse)
err := c.ExecRaw(func(c *client.Client) error {
return client.SendUnary(c, common.CallMethodInfo{
Service: "CustomService",
Name: "CustomRPC",
}, req, resp)
})
// ...
Close the connection:
err := c.Close()
// ...
Note that it's not allowed to override Client behaviour directly: the parameters
for the all operations are write-only and the results of the all operations are
read-only. To be able to override client behavior (e.g. for tests), abstract it
with an interface:
import "github.com/nspcc-dev/neofs-sdk-go/client"
type NeoFSClient interface {
// Operations according to the application needs
CreateContainer(context.Context, container.Container) error
// ...
}
type client struct {
c *client.Client
}
func (x *client) CreateContainer(context.Context, container.Container) error {
// ...
}
