	// PlainOffset is 0 for a migrated object.
	PlainOffset       int64
	CreatedAt         *time.Time // TODO: make it non-nilable after we migrate all existing segments to have creation time
	EncryptedETag     []byte
	EncryptedKeyNonce []byte
	EncryptedKey      []byte
}

SegmentPositionInfo contains information for segment position.

type StreamIDCursor 

type StreamIDCursor struct {
	StreamID uuid.UUID
}

StreamIDCursor is a cursor used during iteration through streamIDs of a pending object.

type StreamRange 

type StreamRange struct {
	PlainStart int64
	PlainLimit int64 // limit is exclusive
}

StreamRange allows to limit stream positions based on the plain offsets.

type StreamVersionID added in v1.95.1 

type StreamVersionID uuid.UUID

StreamVersionID represents combined Version and StreamID suffix for purposes of public API. First 8 bytes represents Version and rest are object StreamID suffix. TODO(ver): we may consider renaming this type to VersionID but to do that we would need to rename metabase.Version into metabase.SequenceNumber/metabase.Sequence to avoid confusion.

func StreamVersionIDFromBytes added in v1.95.1 

func StreamVersionIDFromBytes(bytes []byte) (_ StreamVersionID, err error)

StreamVersionIDFromBytes decodes stream version id from bytes.

func (StreamVersionID) Bytes added in v1.95.1 

func (s StreamVersionID) Bytes() []byte

Bytes returnes stream version id bytes.

func (StreamVersionID) StreamIDSuffix added in v1.95.1 

func (s StreamVersionID) StreamIDSuffix() []byte

StreamIDSuffix returns StreamID suffix encoded into stream version id.

func (StreamVersionID) Version added in v1.95.1 

func (s StreamVersionID) Version() Version

Version returns Version encoded into stream version id.

type TableStats added in v1.32.2 

type TableStats struct {
	SegmentCount int64
}

TableStats contains information about the metabase status.

type UpdateObjectLastCommittedMetadata added in v1.91.2 

type UpdateObjectLastCommittedMetadata struct {
	ObjectLocation
	StreamID uuid.UUID

	EncryptedMetadata             []byte
	EncryptedMetadataNonce        []byte
	EncryptedMetadataEncryptedKey []byte
}

UpdateObjectLastCommittedMetadata contains arguments necessary for replacing an object metadata.

func (*UpdateObjectLastCommittedMetadata) Verify added in v1.91.2 

func (obj *UpdateObjectLastCommittedMetadata) Verify() error

Verify object stream fields.

type UpdateSegmentPieces 

type UpdateSegmentPieces struct {
	StreamID uuid.UUID
	Position SegmentPosition

	OldPieces Pieces

	NewRedundancy storj.RedundancyScheme
	NewPieces     Pieces

	NewRepairedAt time.Time // sets new time of last segment repair (optional).
}

UpdateSegmentPieces contains arguments necessary for updating segment pieces.

type VerifySegment added in v1.64.1 

type VerifySegment struct {
	StreamID uuid.UUID
	Position SegmentPosition

	CreatedAt  time.Time
	RepairedAt *time.Time

	RootPieceID storj.PieceID
	Redundancy  storj.RedundancyScheme

	AliasPieces AliasPieces
}

VerifySegment result of listing segments for verifying remote segments.

type Version 

type Version int64

Version is used to uniquely identify objects with the same key.
