Crate hashkit 

Unified non-cryptographic hash functions for performance-sensitive crates.

The crate exposes three small, dependency-free building blocks:

• fnv for stable FNV-1a hashing, including the flashsieve-compatible two-byte fast path.
• splitmix for high-quality seed finalization and compact pair hashing.
• wyhash for fast bulk hashing of arbitrary byte slices.
• blake3_hash for stable, content-addressed streaming hashing using BLAKE3.

Examples

use hashkit::{bloom_hash_pair, hash_to_index};

let (h1, h2) = bloom_hash_pair(b'a', b'b');
let slot = hash_to_index(h1 ^ h2, 1024);

assert!(slot < 1024);

Modules

Functions
