Struct Hasher64_1

pub struct Hasher64_1 { /* private fields */ }

An implementation of std::hash::Hasher.

Example

use std::hash::Hasher;

use fasthash::{metro::crc::Hasher64_1, FastHasher};

let mut h = Hasher64_1::new();

h.write(b"hello");
assert_eq!(h.finish(), 6455825309044375053);

h.write(b"world");
assert_eq!(h.finish(), 15512397028293617890);
