Struct Sha256 

pub struct Sha256 { /* private fields */ }

SHA-256 hasher.

Implementations

impl Sha256

pub fn fill(b: u8) -> <Self as Hasher>::Digest

Convenience function for testing that creates an easily recognizable digest by repeating a single byte.

Trait Implementations

impl Debug for Sha256

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Sha256

fn default() -> Self

Returns the “default value” for a type.

impl Hasher for Sha256

type Digest = Digest

Digest generated by the hasher.

fn hash(parts: &[&[u8]]) -> Self::Digest

Hash the concatenation of parts in a single shot.

fn hash_pair( left: &[&[u8]], right: &[&[u8]], _strategy: &impl Strategy, ) -> (Self::Digest, Self::Digest)

Hash two messages, each given as a concatenation of parts, in a single shot, splitting the work across strategy when the hash function allows it.

fn hash_many<M: AsRef<[u8]> + Sync>( messages: &[M], strategy: &impl Strategy, ) -> Vec<Self::Digest>

Hash multiple independent byte slices, splitting them across strategy.

fn update(&mut self, message: &[u8]) -> &mut Self

Append bytes to the hasher’s running state.

fn finalize(self) -> (Self, Self::Digest)

Consume the hasher, returning a freshly-reset hasher alongside the digest of everything written so far.

fn hash_across(parts: &[&[u8]], _strategy: &impl Strategy) -> Self::Digest

Hash the concatenation of parts in a single shot, splitting the work across strategy when the hash function allows it.
