Trait XofReader

trait XofReader

Trait for reader types which are used to extract extendable output from a XOF (extendable-output function) result.

Required Methods

fn read(self: &mut Self, buffer: &mut [u8])

Read output into the buffer. Can be called an unlimited number of times.

Provided Methods

fn read_boxed(self: &mut Self, n: usize) -> Box<[u8]>

Read output into a boxed slice of the specified size.

Can be called an unlimited number of times in combination with read.

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