raylib-rs

raylib-rs is a Rust binding for raylib 5.5. It currently targets Rust toolchain version 1.78 or higher.

Please checkout the showcase directory to find usage examples!

Though this binding tries to stay close to the simple C API, it makes some changes to be more idiomatic for Rust.

Most development happens over at: https://github.com/raylib-rs/raylib-rs

Resources are automatically cleaned up when they go out of scope (or when std::mem::drop is called). This is essentially RAII. This means that "Unload" functions are not exposed (and not necessary unless you obtain a Weak resource using make_weak()).
Most of the Raylib API is exposed through RaylibHandle, which is for enforcing that Raylib is only initialized once, and for making sure the window is closed properly. RaylibHandle has no size and goes away at compile time. Because of mutability rules, Raylib-rs is thread safe!
A RaylibHandle and RaylibThread are obtained through raylib::init_window(...) or through the newer init() function which will allow you to build up some window options before initialization (replaces set_config_flags). RaylibThread should not be sent to any other threads, or used in a any syncronization primitives (Mutex, Arc) etc.
Manually closing the window is unnecessary, because CloseWindow is automatically called when RaylibHandle goes out of scope.
Model::set_material, Material::set_shader, and MaterialMap::set_texture methods were added since one cannot set the fields directly. Also enforces correct ownership semantics.
Font::from_data, Font::set_chars, and Font::set_texture methods were added to create a Font from loaded CharInfo data.
SubText and FormatText are omitted, and are instead covered by Rust's string slicing and Rust's format! macro, respectively.

Build Dependencies

Requires glfw, cmake, and curl. Tips on making things work smoothly on all platforms is appreciated. Follow instructions for building raylib for your platform here

Add the dependency to your Cargo.toml:

[dependencies]
raylib = { version = "5.5" }

Start coding!

use raylib::prelude::*;

fn main() {
    let (mut rl, thread) = raylib::init()
        .size(640, 480)
        .title("Hello, World")
        .build();

    while !rl.window_should_close() {
        let mut d = rl.begin_drawing(&thread);

        d.clear_background(Color::WHITE);
        d.draw_text("Hello, world!", 12, 12, 20, Color::BLACK);
    }
}

NixOS

To use raylib-rs on NixOS there's a provided nix-shell file shell.nix at the root of the repo that should get you up and running, which can be used like so:

nix-shell ./shell.nix

You'll also need to enable the Wayland feature on the raylib crate:

cargo add raylib -F wayland

Contributions are welcome to improve or fix the shell.nix!

Tech Notes

Structs holding resources have RAII/move semantics, including: Image, Texture2D, RenderTexture2D, Font, Mesh, Shader, Material, and Model.
Wave, Sound, Music, and AudioStream have lifetimes bound to AudioHandle.
Functions dealing with string data take in &str and/or return an owned String, for the sake of safety. The exception to this is the gui draw functions which take &CStr to avoid per frame allocations. The rstr! macro helps make this easy.
In C, LoadFontData returns a pointer to a heap-allocated array of CharInfo structs. In this Rust binding, said array is copied into an owned Vec<CharInfo>, the original data is freed, and the owned Vec is returned.
In C, LoadDroppedFiles returns a pointer to an array of strings owned by raylib. Again, for safety and also ease of use, this binding copies said array into a Vec<String> which is returned to the caller.
I've tried to make linking automatic, though I've only tested on Windows 10, Ubuntu, and MacOS 15. Other platforms may have other considerations.
OpenGL 3.3, 2.1, and ES 2.0 may be forced via adding ["opengl_33"], ["opengl_21"] or ["opengl_es_20] to the features array in your Cargo.toml dependency definition.

Building from source

Clone repository: git clone --recurse-submodules
cargo build

If building for Wayland on Linux

Install these packages:
libglfw3-dev wayland-devel libxkbcommon-devel wayland-protocols wayland-protocols-devel libecm-dev

Note that this may not be a comprehensive list, please add details for your distribution or expand on these packages if you believe this to be incomplete.

Enable wayland by adding features=["wayland"] to your dependency definition

Cross-compiling using `cross`

Cross compiling with raylib-rs can be made easier with cross. See more on the wiki

Extras

In addition to the base library, there is also a convenient ease module which contains various interpolation/easing functions ported from raylib's easings.h, as well as a Tween struct to assist in using these functions.
Equivalent math and vector operations, ported from raymath.h, are impled on the various Vector and Matrix types. Operator overloading is used for more intuitive design.

Testing

The raylib-test crate tests the bindings by opening a window, and checking the results of various functions. It requires nightly to use.
