Types

type Deltas

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

Deltas tracks the trie deltas, for example deleted node hashes.

func New

func New() *Deltas

New returns a new Deltas struct.

func (*Deltas) DeepCopy

func (d *Deltas) DeepCopy() (deepCopy *Deltas)

DeepCopy returns a deep copy of the deltas.

func (*Deltas) Deleted

func (d *Deltas) Deleted() (nodeHashes map[common.Hash]struct{})

Deleted returns a set (map) of all the recorded deleted node hashes. Note the map returned is not deep copied for performance reasons and so it's not safe for mutation.

func (*Deltas) MergeWith

func (d *Deltas) MergeWith(deltas Getter)

MergeWith merges the deltas given as argument in the receiving deltas struct.

func (*Deltas) RecordDeleted

func (d *Deltas) RecordDeleted(nodeHash common.Hash)

RecordDeleted records a node hash as deleted.

type Getter

type Getter interface {
	Deleted() (nodeHashes map[common.Hash]struct{})
}

Getter gets deleted node hashes.
