![Github Repo Issues](https://img.shields.io/github/issues/NikoMalik/wyhash?style=flat) ![GitHub Repo stars](https://img.shields.io/github/stars/NikoMalik/wyhash?style=social)

🚀 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

```zig

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*

```zig

.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*

```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

```zig

const wyhash = @import("wyhash")

```

#  📦 Installation/2

```bash

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.
