Provided methods

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

This is supported on 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, n: usize) -> Box<[u8]>

This is supported on 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.
