Expand description

Convenience wrapper trait covering functionality of cryptographic hash functions with fixed output size.

This trait wraps Update, FixedOutput, Default, and HashMarker traits and provides additional convenience methods.

Required Methods§

source

fn new() -> Self

Create new hasher instance.

source

fn new_with_prefix(data: impl AsRef<[u8]>) -> Self

Create new hasher instance which has processed the provided data.

source

fn update(&mut self, data: impl AsRef<[u8]>)

Process data, updating the internal state.

source

fn chain_update(self, data: impl AsRef<[u8]>) -> Self

Process input data in a chained manner.

source

fn finalize(self) -> Output<Self>

Retrieve result and consume hasher instance.

source

fn finalize_into(self, out: &mut Output<Self>)

Write result into provided array and consume the hasher instance.

source

fn finalize_reset(&mut self) -> Output<Self>
where Self: FixedOutputReset,

Retrieve result and reset hasher instance.

source

fn finalize_into_reset(&mut self, out: &mut Output<Self>)
where Self: FixedOutputReset,

Write result into provided array and reset the hasher instance.

source

fn reset(&mut self)
where Self: Reset,

Reset hasher instance to its initial state.

source

fn output_size() -> usize

Get output size of the hasher

source

fn digest(data: impl AsRef<[u8]>) -> Output<Self>

Compute hash of data.

Object Safety§

This trait is not object safe.
