Constants

View Source 
const CurrentFormat uint32 = 2

CurrentFormat is the currently used format for snapshots. Snapshots using the same format must be identical across all nodes for a given height, so this must be bumped when the binary snapshot output changes.

Variables

	// ErrUnknownFormat is returned when an unknown format is used.
	ErrUnknownFormat = errors.New("unknown snapshot format")

	// ErrChunkHashMismatch is returned when chunk hash verification failed.
	ErrChunkHashMismatch = errors.New("chunk hash verification failed")

	// ErrInvalidMetadata is returned when the snapshot metadata is invalid.
	ErrInvalidMetadata = errors.New("invalid snapshot metadata")

Functions

func WriteExtensionItem added in v0.45.2 

func WriteExtensionItem(protoWriter protoio.Writer, item []byte) error

Types

type ExtensionSnapshotter added in v0.45.2 

type ExtensionSnapshotter interface {
	Snapshotter

	// SnapshotName returns the name of snapshotter, it should be unique in the manager.
	SnapshotName() string

	// SnapshotFormat returns the default format the extension snapshotter use to encode the
	// payloads when taking a snapshot.
	// It's defined within the extension, different from the global format for the whole state-sync snapshot.
	SnapshotFormat() uint32

	// SupportedFormats returns a list of formats it can restore from.
	SupportedFormats() []uint32
}

ExtensionSnapshotter is an extension Snapshotter that is appended to the snapshot stream. ExtensionSnapshotter has an unique name and manages it's own internal formats.
