4KB
This crate provides wrappers for Hasher
that change the endianness
used when hashing primitive numeric types.
Installation
This crate works with Cargo and is on
crates.io. Add it to your Cargo.toml
with:
[dependencies]
endianhasher = "0.1"
Use the crate like:
extern crate endian_hasher;
use std::hash::{Hasher, SipHasher24};
use endianhasher::{HasherToLE, HasherToBE};
let mut h1 = HasherToLE(SipHasher24::new_with_keys(k0,k1));
-3i64.hash(&mut h1);
h1.finish()
lib.rs
:
These simple wrapper types for Hasher
change the endianness
used when hashing primitive numeric types.
Examples
use std::collections::hash_map::DefaultHasher;
use std::hash::Hasher;
use endian_hasher::*;
assert_eq!( {
let mut h1 = HasherToLE(DefaultHasher::new());
h1.write_i16(-3);
h1.finish()
}, {
let mut h0 = DefaultHasher::new();
h0.write_i16( i16::to_le(-3) );
h0.finish()
} );
assert_eq!( {
let mut h1 = HasherToBE(DefaultHasher::new());
h1.write_u32(79);
h1.finish()
}, {
let mut h0 = DefaultHasher::new();
h0.write_u32( 79u32.to_be() );
h0.finish()
} );
assert_eq!( {
let mut h1 = HasherSwapBytes(DefaultHasher::new());
h1.write_u64(0x12345678);
h1.finish()
}, {
let mut h0 = DefaultHasher::new();
h0.write_u64( u64::swap_bytes(0x12345678) );
h0.finish()
} );
