Struct Hasher64 

pub struct Hasher64(/* private fields */);

An implementation of std::hash::Hasher.

Example

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

use fasthash::{xx::Hasher64, FastHasher, StreamHasher};

let mut h = Hasher64::new();

h.write(b"hello");
assert_eq!(h.finish(), 2794345569481354659);

h.write(b"world");
assert_eq!(h.finish(), 9228181307863624271);

h.write_stream(&mut Cursor::new(&[0_u8; 4567][..])).unwrap();
assert_eq!(h.finish(), 6304142433100597454);
