Struct fasthash::xx::Hasher32

pub struct Hasher32(_);

An implementation of std::hash::Hasher.

Example

use std::hash::Hasher;
use std::io::Cursor;

use fasthash::{xx::Hasher32, FastHasher, StreamHasher};

let mut h = Hasher32::new();

h.write(b"hello");
assert_eq!(h.finish(), 4211111929);

h.write(b"world");
assert_eq!(h.finish(), 593682946);

h.write_stream(&mut Cursor::new(&[0_u8; 4567][..])).unwrap();
assert_eq!(h.finish(), 2113960620);
