Crate fx_hash 

A speedy, non-cryptographic hashing algorithm used by rustc.

Fork of rustc-hash. This is for personal usage only, please use rustc-hash.

Example

use fx_hash::{FxHashMap, FxHashMapExt};

let mut map: FxHashMap<u32, u32> = FxHashMap::new();
map.insert(22, 44);

Structs

FxBuildHasher

An implementation of BuildHasher that produces FxHashers.

FxHasher

A speedy hash algorithm for use within rustc. The hashmap in liballoc by default uses SipHash which isn’t quite as speedy as we want. In the compiler we’re not really worried about DOS attempts, so we use a fast non-cryptographic hash.

FxSeededState

FxSeededState is an alternative state for HashMap types, allowing to use FxHasher with a set seed.

Traits

FxHashMapExt

A trait to add a new constructor for FxHashMap.

FxHashSetExt

A trait to add a new constructor for FxHashSet.

Type Aliases

FxHashMap

Type alias for a hash map that uses the Fx hashing algorithm.

FxHashMapSeed

Type alias for a hashmap using the fx hash algorithm with FxSeededState.

FxHashSet

Type alias for a hash set that uses the Fx hashing algorithm.

FxHashSetSeed

Type alias for a hashmap using the fx hash algorithm with FxSeededState.
