Abstraction around hashing

Required Associated Types

type Output: HashOutput

The hash type produced.

Required Methods

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

The ordered Patricia tree root of the given input.

fn trie_root( input: Vec<(Vec<u8>, Vec<u8>)>, 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::Output

where S: Encode,

Produce the hash of some codec-encodable value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
