Types

type Database

type Database interface {
	PreimageStore

	// Reader returns a node reader associated with the specific state.
	// An error will be returned if the specified state is not available.
	Reader(stateRoot common.Hash) (Reader, error)
}

Database wraps the methods of a backing trie store.

type PreimageStore

type PreimageStore interface {
	// Preimage retrieves the preimage of the specified hash.
	Preimage(hash common.Hash) []byte

	// InsertPreimage commits a set of preimages along with their hashes.
	InsertPreimage(preimages map[common.Hash][]byte)
}

PreimageStore wraps the methods of a backing store for reading and writing trie node preimages.

type Reader

type Reader interface {
	// Node retrieves the trie node blob with the provided trie identifier,
	// node path and the corresponding node hash. No error will be returned
	// if the node is not found.
	//
	// Don't modify the returned byte slice since it's not deep-copied and
	// still be referenced by database.
	Node(owner common.Hash, path []byte, hash common.Hash) ([]byte, error)
}

Reader wraps the Node method of a backing trie reader.
