WYHASH - Zig Implementation

🚀 Overview

Wyhash is a fast, high-quality, portable non-cryptographic hash function known for its exceptional speed and randomness quality. This repository provides a native Zig implementation of Wyhash.Project is also open for people to add to and improve. Please check the issues to view requested features

Why Wyhash?

• ✅ Extremely fast performance across different architectures
• ✅ High-quality randomness and strong avalanche effect
• ✅ Minimal code size and efficient memory usage
• ✅ Used in databases, networking, and high-performance applications

🛠 Basic Usage

const wyhash = @import("wyhash");
const std = @import("std");

pub fn main() !void {
    const r: u64 = 0x001020120;

    const res = wyhash._whash("🔥Hello World!", r);
    std.debug.print("wyhash(\"🔥Hello World!\", {}) = {}\n", .{ r, res });
}

📦 Installation

Add this to your build.zig.zon

.dependencies = .{
    .wyhash = .{
        .url = "https://github.com/NikoMalik/wyhash/archive/refs/heads/main.tar.gz",
        //the correct hash will be suggested by zig
    }
}

And add this to you build.zig

    const wyhash = b.dependency("wyhash", .{
        .target = target,
        .optimize = optimize,
    });
    exe_mod.addImport("wyhash", wyhash.module("wyhash"));

You can then import the library into your code like this

const wyhash = @import("wyhash")

📦 Installation/2

git clone https://github.com/NikoMalik/wyhash.git
mv wyhash /path/to/your/project/directory

🔥 Benchmarks

Wyhash is one of the fastest hash functions available. Benchmarks against MurmurHash3, XXHash, and CityHash show superior performance in most cases.
