Expand description

Defines a cryptographic hash function.

This trait defined hash procedures for the following inputs:

  • A sequence of bytes.
  • Two digests - this is intended for use in Merkle tree constructions.
  • A digests and a u64 value - this intended for use in PRNG or PoW contexts.

Associated Types

Specifies a digest type returned by this hasher.

Required methods

Returns a hash of the provided sequence of bytes.

Returns a hash of two digests. This method is intended for use in construction of Merkle trees.

Returns hash(seed || value). This method is intended for use in PRNG and PoW contexts.
