hash32

Trait Hasher

Source 
pub trait Hasher: Hasher {
    // Required method
    fn finish32(&self) -> u32;
}
Expand description

An extension of core::hash::Hasher for 32-bit hashers.

For hashers that implement this trait, the core::hash::Hasher::finish method should return a zero-extended version of the result from Hasher::finish32.

§Contract

Implementers of this trait must not perform any 64-bit (or 128-bit) operation while computing the hash.

§Examples

use core::hash::Hasher as _;
use hash32::{FnvHasher, Hasher as _};

let mut hasher: FnvHasher = Default::default();

hasher.write_u32(1989);
hasher.write_u8(11);
hasher.write_u8(9);
hasher.write(b"Huh?");

println!("Hash is {:x}!", hasher.finish32());

Required Methods§

Source

fn finish32(&self) -> u32

The equivalent of core::hash::Hasher::finish for 32-bit hashers.

This returns the hash directly; core::hash::Hasher::finish zero-extends the finish32 result to 64-bits for compatibility.
