1.0.0[][src]Struct std::hash::SipHasher

pub struct SipHasher(_);
Deprecated since 1.13.0:

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]

Deprecated since 1.13.0:

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]

Deprecated since 1.13.0:

use std::collections::hash_map::DefaultHasher instead

Creates a SipHasher that is keyed off the provided keys.
