Struct std::hash::SipHasher
pub struct SipHasher(_);
use std::collections::hash_map::DefaultHasher
instead
An implementation of SipHash 2-4.
See: https://131002.net/siphash/
SipHash is a general-purpose hashing function: it runs at a good speed (competitive with Spooky and City) and permits strong keyed hashing. This lets you key your hash tables from a strong RNG, such as rand::os::OsRng
.
Although the SipHash algorithm is considered to be generally strong, it is not intended for cryptographic purposes. As such, all cryptographic uses of this implementation are strongly discouraged.
Implementations
impl SipHasher
pub fn new() -> SipHasher
use std::collections::hash_map::DefaultHasher
instead
Creates a new SipHasher
with the two initial keys set to 0.
pub fn new_with_keys(key0: u64, key1: u64) -> SipHasher
use std::collections::hash_map::DefaultHasher
instead
Creates a SipHasher
that is keyed off the provided keys.
