GLFW bindings and wrapper for The Rust Programming Language.
Example
extern crate glfw;
use glfw::{Action, Context, Key};
fn main() {
let mut glfw = glfw::init(glfw::fail_on_errors).unwrap();
let (mut window, events) = glfw.create_window(300, 300, "Hello this is window", glfw::WindowMode::Windowed)
.expect("Failed to create GLFW window.");
window.set_key_polling(true);
window.make_current();
while !window.should_close() {
glfw.poll_events();
for (_, event) in glfw::flush_messages(&events) {
handle_window_event(&mut window, event);
}
}
}
fn handle_window_event(window: &mut glfw::Window, event: glfw::WindowEvent) {
match event {
glfw::WindowEvent::Key(Key::Escape, _, Action::Press, _) => {
window.set_should_close(true)
}
_ => {}
}
}
Using glfw-rs
Prerequisites
Make sure you have compiled and installed GLFW 3.x.
You might be able to find it on your package manager, for example on OS X:
brew install glfw3
(you may need to run brew tap homebrew/versions
).
If not you can download and build the library
from the source supplied on the
GLFW website. Note that if you compile GLFW with CMake on Linux, you will have
to supply the -DCMAKE_C_FLAGS=-fPIC
argument. You may install GLFW to your
PATH
, otherwise you will have to specify the directory containing the library
binaries when you call make
or make lib
:
GLFW_LIB_DIR=path/to/glfw/lib/directory make
Including glfw-rs in your project
Add this to your Cargo.toml
:
[dependencies.glfw]
version = "*"
On Windows
By default, glfw-rs
will try to compile the glfw
library. If you want to link to your custom
build of glfw
or if the build doesn't work (which is probably the case on Windows), you can
disable this:
[dependencies.glfw]
version = "*"
default-features = false
Raw window handle 0.5.0 compatibility
By default, glfw-rs
uses raw-window-handle at v0.6.0. If your project is depending on glfw-rs
with raw-window-handle v0.5.0, then use this line in your Cargo.toml:
glfw = { version = 0.56.0 , default-features = false, features = ["with-window-handle-v0-5"] }

glfw-rs in use
glfw-rs with other graphical APIs
In certain circumstances OpenGL which GLFW uses can conflict with the new handle that the graphical API is also trying to use, causing crashes, to fix this add
glfw.window_hint(WindowHint::ClientApi(ClientApiHint::NoApi));
before creating the window. If using this however you cannot use certain built-in functions,
such as window.swap_buffers()
, window.make_current()
, and glfw.set_swap_interval()
, but
these should have equivalents provided by the graphical API.
