Modification of the Digest trait suitable for trait objects.

Required Methods

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

Digest input data.

This method can be called repeatedly for use with streaming messages.

fn finalize_into(self, buf: &mut [u8]) -> Result<(), InvalidBufferSize>

Write result into provided array and consume the hasher instance.

Returns error if buffer length is not equal to output_size.

fn finalize_into_reset(
    &mut self,
    out: &mut [u8]
) -> Result<(), InvalidBufferSize>

Write result into provided array and reset the hasher instance.

Returns error if buffer length is not equal to output_size.

fn reset(&mut self)

Reset hasher instance to its initial state.

fn output_size(&self) -> usize

Get output size of the hasher

fn box_clone(&self) -> Box<dyn DynDigest + 'static, Global>

Clone hasher state into a boxed trait object

Provided Methods

fn finalize_reset(&mut self) -> Box<[u8], Global>

Retrieve result and reset hasher instance

fn finalize(self: Box<Self, Global>) -> Box<[u8], Global>

Retrieve result and consume boxed hasher instance
