}Expand description
Trait for hash functions with variable-size output able to reset themselves.
Required Methods
fn finalize_variable_reset(
&mut self,
out: &mut [u8]
) -> Result<(), InvalidBufferSize>
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().

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.
