Functions

func CollectMembers

func CollectMembers(
	ctx context.Context,
	collector relations.Executor,
	cnr cid.ID,
	members []oid.ID,
	tokens relations.Tokens,
	calcHomoHash bool,
	signer user.Signer,
) (*storagegroup.StorageGroup, error)

CollectMembers creates new storage group structure and fills it with information about members collected via HeadReceiver.

Resulting storage group consists of physically stored objects only.

Types

type Result

type Result struct {
	// contains filtered or unexported fields
}

Result represents report on the results of the data audit in NeoFS system.

Result is mutually binary-compatible with github.com/epicchainlabs/epicchain-api-go/v2/audit.DataAuditResult message. See Marshal / Unmarshal methods.

Instances can be created using built-in var declaration.

Example

package main

import (
	"github.com/epicchainlabs/epicchain-sdk-go/audit"
	cid "github.com/epicchainlabs/epicchain-sdk-go/container/id"
)

func main() {
	var res audit.Result
	var cnr cid.ID

	res.ForEpoch(32)
	res.ForContainer(cnr)
	// ...
	res.Complete()

	// Result instances can be stored in a binary format on client side.
	data := res.Marshal()

	// ...

	// Result instances can be restored from a binary format on server side.
	var auditResult audit.Result
	_ = auditResult.Unmarshal(data)
}

func (Result) AuditorKey

func (r Result) AuditorKey() []byte

AuditorKey returns public key of the auditing NeoFS Inner Ring node in a NeoFS binary key format.

Zero Result has nil key.

The value returned shares memory with the structure itself, so changing it can lead to data corruption. Make a copy if you need to change it.

The resulting slice of bytes is a serialized compressed public key. See [elliptic.MarshalCompressed]. Use [neofsecdsa.PublicKey.Decode] to decode it into a type-specific structure.

See also Result.SetAuditorKey.

func (*Result) Complete

func (r *Result) Complete()

Complete marks the data audit associated with the Result as completed.

See also Completed.

func (Result) Completed

func (r Result) Completed() bool

Completed returns completion state of the data audit associated with the Result.

Zero Result corresponds to incomplete data audit.

See also Complete.

func (Result) Container

func (r Result) Container() (cid.ID, bool)

Container returns identifier of the container with which the data audit Result is associated and a bool that indicates container ID field presence in the Result.

Zero Result does not have container ID.

See also ForContainer.

func (Result) Epoch

func (r Result) Epoch() uint64

Epoch returns NeoFS epoch when the data associated with the Result was audited.

Zero Result has zero epoch.

See also ForEpoch.

func (Result) Failures

func (r Result) Failures() uint32

Failures returns number of sampled objects under audit stored in a way not confirming placement policy or not found at all when checking Proof-of-Placement.

Zero result has zero failures.

See also SetFailures.

func (*Result) ForContainer

func (r *Result) ForContainer(cnr cid.ID)

ForContainer sets identifier of the container with which the data audit Result is associated.

See also Container.

func (*Result) ForEpoch

func (r *Result) ForEpoch(epoch uint64)

ForEpoch specifies NeoFS epoch when the data associated with the Result was audited.

See also Epoch.

func (Result) Hits

func (r Result) Hits() uint32

Hits returns number of sampled objects under audit placed in an optimal way according to the container's placement policy when checking Proof-of-Placement.

Zero result has zero hits.

See also SetHits.

func (Result) IterateFailedStorageGroups

func (r Result) IterateFailedStorageGroups(f func(oid.ID) bool)

IterateFailedStorageGroups is similar to IteratePassedStorageGroups but for failed groups.

See also SubmitFailedStorageGroup.

func (Result) IterateFailedStorageNodes

func (r Result) IterateFailedStorageNodes(f func([]byte) bool)

IterateFailedStorageNodes is similar to IteratePassedStorageNodes but for failed nodes.

See also SubmitPassedStorageNodes.

func (Result) IteratePassedStorageGroups

func (r Result) IteratePassedStorageGroups(f func(oid.ID) bool)

IteratePassedStorageGroups iterates over all storage groups that passed Proof-of-Retrievability audit check and passes them into f. Breaks on f's false return, f MUST NOT be nil.

Zero Result has no passed storage groups and doesn't call f.

See also SubmitPassedStorageGroup.

func (Result) IteratePassedStorageNodes

func (r Result) IteratePassedStorageNodes(f func([]byte) bool)

IteratePassedStorageNodes iterates over all storage nodes that passed at least one Proof-of-Data-Possession audit check and passes their public keys into f. Breaks on f's false return.

f MUST NOT be nil and MUST NOT mutate parameter passed into it at least until the end of using the Result.

Zero Result has no passed storage nodes and doesn't call f.

See also SubmitPassedStorageNode.

func (*Result) Marshal

func (r *Result) Marshal() []byte

Marshal encodes Result into a canonical NeoFS binary format (Protocol Buffers with direct field order).

Writes version.Current() protocol version into the resulting message if Result hasn't been already decoded from such a message using Unmarshal.

See also Unmarshal.

func (Result) Misses

func (r Result) Misses() uint32
