Expand description

Trait for hash functions with variable-size output able to reset themselves.

Required Methods§

source

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

Write result into the output buffer and reset the hasher state.

Returns Err(InvalidOutputSize) if out size is not equal to self.output_size().

Provided Methods§

source

fn finalize_boxed_reset(&mut self) -> Box<[u8]>

Retrieve result into a boxed slice and reset the hasher state.

Box<[u8]> is used instead of Vec<u8> to save stack space, since they have size of 2 and 3 words respectively.
