Trait Hasher 

pub trait Hasher {
    type Output;

    // Required methods
    fn clean(&mut self) -> &mut Self;
    fn finish(&self) -> Result<Self::Output>;
    fn include(&mut self, data: impl AsRef<[u8]>) -> &mut Self;
}

A Hasher defines a common interface for defining specific hashing algorithm.

Required Associated Types

type Output

the output type of the hasher

Required Methods

fn clean(&mut self) -> &mut Self

reset the hasher to its initial state

fn finish(&self) -> Result<Self::Output>

finalize the hash and return the result

fn include(&mut self, data: impl AsRef<[u8]>) -> &mut Self

update the hasher with new data

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.
