std::hash::SipHasher
Struct std::hash::SipHasher
pub struct SipHasher(_);
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]
fn new() -> SipHasher
Creates a new SipHasher with the two initial keys set to 0.
fn new_with_keys(key0: u64, key1: u64) -> SipHasher
Creates a SipHasher that is keyed off the provided keys.
