In NeoFS every operation can fail on multiple levels, so a single `error` doesn't suffice,
e.g. consider a case when object was put on 4 out of 5 replicas. Thus, all request execution
details are contained in `Status` returned from every RPC call. dApp can inspect them
if needed and perform any desired action. In the case above we may want to report
these details to the user as well as retry an operation, possibly with different parameters.
Status wire-format is extendable and each node can report any set of details it wants.
The set of reserved status codes can be found in
[FrostFS API](https://git.frostfs.info/TrueCloudLab/frostfs-api/src/branch/master/status/types.proto). There is also
a `client.PrmInit.ResolveFrostFSFailures()` to seamlessly convert erroneous statuses into Go error type.

Package accounting provides primitives to perform accounting operations in FrostFS.
Decimal type provides functionality to process user balances. For example, when
working with Fixed8 balance precision:
var dec accounting.Decimal
dec.SetValue(val)
dec.SetPrecision(8)
Instances can be also used to process FrostFS API V2 protocol messages
(see neo.fs.v2.accounting package in https://git.frostfs.info/TrueCloudLab/frostfs-api).
On client side:
import "git.frostfs.info/TrueCloudLab/frostfs-api-go/v2/accounting"
var msg accounting.Decimal
dec.WriteToV2(&msg)
// send msg
On server side:
// recv msg
var dec accounting.Decimal
dec.ReadFromV2(msg)
// process dec
Using package types in an application is recommended to potentially work with
different protocol versions with which these types are compatible.

/*
Package checksum provides primitives to work with checksums.
Checksum is a basic type of data checksums.
For example, calculating checksums:
// retrieving any payload for hashing
var sha256Sum Checksum
Calculate(&sha256Sum, SHA256, payload) // sha256Sum contains SHA256 hash of the payload
var tzSum Checksum
Calculate(&tzSum, TZ, payload) // tzSum contains TZ hash of the payload
Using package types in an application is recommended to potentially work with
different protocol versions with which these types are compatible.
