Required methods

fn finalize_xof(self) -> Self::Reader[src]

Provided methods

fn digest_xof(input: impl AsRef<[u8]>, output: &mut [u8])[src]

Compute hash of data and write it to output.

fn finalize_boxed(self, output_size: usize) -> Box<[u8]>[src]

This is supported on crate feature alloc only.

Retrieve result into a boxed slice of the specified size and consume the hasher.

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

fn finalize_boxed_reset(&mut self, output_size: usize) -> Box<[u8]>[src]

This is supported on crate feature alloc only.

Retrieve result into a boxed slice of the specified size and reset the hasher's state.

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