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.

Functions

func WriteExtensionItem 

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

WriteExtensionItem writes an item payload for current extension snapshotter.

Types

type ExtensionSnapshotter 

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.

Snapshotter is something that can create and restore snapshots, consisting of streamed binary chunks - all of which must be read from the channel and closed. If an unsupported format is given, it must return ErrUnknownFormat (possibly wrapped with fmt.Errorf).
