Trait libp2p::multihash::StatefulHasher

pub trait StatefulHasher: Default + Send + Sync {
    type Size: Size;
    type Digest: Digest<Self::Size>;
    fn update(&mut self, input: &[u8]);
    fn finalize(&self) -> Self::Digest;
    fn reset(&mut self);
}

Trait implemented by a hash function implementation.

Associated Types

type Size: Size

The maximum Digest size for that hasher (it is stack allocated).

type Digest: Digest<Self::Size>

The Digest type to distinguish the output of different Hasher implementations.

Required methods

fn update(&mut self, input: &[u8])

Consume input and update internal state.

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

Returns the final digest.

fn reset(&mut self)

Reset the internal hasher state.
