Struct std::hash::SipHasher 1.0.0
[−]
[src]
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 hashtables 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.
Methods
impl SipHasher
[src]
pub fn new() -> SipHasher
[src][−]
: 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
[src][−]
: use std::collections::hash_map::DefaultHasher
instead
Creates a SipHasher
that is keyed off the provided keys.
