Types

type Checkpoint

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

func FromCheckpoint

func FromCheckpoint(file io.Reader) *Checkpoint

func (*Checkpoint) Trie

func (c *Checkpoint) Trie() (*trie.MTrie, error)

Trie loads the execution state trie from the LedgerWAL root checkpoint.

type Index

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

Index implements an execution state trie loader on top of a DPS index, able to restore an execution state trie from the index database.

func FromIndex

func FromIndex(log zerolog.Logger, lib dps.ReadLibrary, db *badger.DB) *Index

FromIndex creates a new index loader, which can restore the execution state from the given index database, using the given library for decoding ledger paths and payloads.

func (*Index) Trie

func (i *Index) Trie() (*trie.MTrie, error)

Trie restores the execution state trie from the DPS index database, as it was when indexing was stopped.
