GLFW on Rust 環境構築

1. 各種インストール

Rust

$ curl https://sh.rustup.rs -sSf | sh

GLFW

$ brew install cmake glfw

2. プロジェクト作成

$ cargo new hello_glfw --bin
$ cd hello_glfw

3. glfw-rs をプロジェクトに追加する

Cargo.toml

[package]
name = "hello_glfw"
version = "0.1.0"
authors = ["Seibe TAKAHASHI"]

[dependencies.glfw]
git = "https://github.com/bjz/glfw-rs.git"

4. glfw-rs のサンプルをビルド

src/main.rs

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)
        }
        _ => {}
    }
}

$ cargo run
