Abstraction around hashing

Required Associated Types§

type Output: HashOutput

The hash type produced.

Required Methods§

fn ordered_trie_root( input: Vec<Vec<u8, Global>, Global>, state_version: StateVersion ) -> Self::Output

The ordered Patricia tree root of the given input.

fn trie_root( input: Vec<(Vec<u8, Global>, Vec<u8, Global>), Global>, state_version: StateVersion ) -> Self::Output

The Patricia tree root of the given mapping.

Provided Methods§

fn hash(s: &[u8]) -> Self::Output

Produce the hash of some byte-slice.

fn hash_of<S>(s: &S) -> Self::Outputwhere S: Encode,

Produce the hash of some codec-encodable value.
