Trait Xof

pub trait Xof: Clone {
    type Reader: XofReader;

    // Required methods
    fn new(s: &[u8]) -> Self;
    fn update(&mut self, data: &[u8]);
    fn finalize_xof(self) -> Self::Reader;

    // Provided method
    fn finalize_xof_into(self, out: &mut [u8]) { ... }
}

A extendable output function (XOF).

Required Associated Types

type Reader: XofReader

Reads output bytes.

Required Methods

fn new(s: &[u8]) -> Self

Creates a new XOF with the customization string s.

fn update(&mut self, data: &[u8])

Updates the running hash with data.

fn finalize_xof(self) -> Self::Reader

Returns the output of the XOF.

Provided Methods

fn finalize_xof_into(self, out: &mut [u8])

Writes the XOF output to out.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
