A collection of hash data

Required Methods

fn has_hash(&self, node: Node) -> bool

Does this hash exist in the collection?

fn hash_for(&self, node: Node) -> Option<Hash<D>>

Get the hash for a given node None if node does not yet exist

Provided Methods

fn prove_inclusion(&self, leaf: Node, log_length: usize) -> InclusionProof<D, V>

Construct an inclusion proof for this log

fn prove_consistency( &self, old_length: usize, new_length: usize ) -> ConsistencyProof<D, V>

Construct a consistency proof for this log

Implementors
