minifb is a cross platform library written in Rust and that makes it easy to setup a window and to (optional) display a 32-bit pixel buffer. It also makes it easy to get input from keyboard and mouse. Notice that minifb is primary designed for prototyping and may not include all the features found in full window handling libraries. An example is the best way to show how it works:

Usage

# Cargo.toml
[dependencies]
minifb = "0.18"

Example

extern crate minifb;

use minifb::{Key, Window, WindowOptions};

const WIDTH: usize = 640;
const HEIGHT: usize = 360;

fn main() {
    let mut buffer: Vec<u32> = vec![0; WIDTH * HEIGHT];

    let mut window = Window::new(
        "Test - ESC to exit",
        WIDTH,
        HEIGHT,
        WindowOptions::default(),
    )
    .unwrap_or_else(|e| {
        panic!("{}", e);
    });

    // Limit to max ~60 fps update rate
    window.limit_update_rate(Some(std::time::Duration::from_micros(16600)));

    while window.is_open() && !window.is_key_down(Key::Escape) {
        for i in buffer.iter_mut() {
            *i = 0; // write something more funny here!
        }

        // We unwrap here as we want this code to exit if it fails. Real applications may want to handle this in a different way
        window
            .update_with_buffer(&buffer, WIDTH, HEIGHT)
            .unwrap();
    }
}

Status

Currently macOS, Linux and Windows (64-bit and 32-bit) are the current supported platforms. X11 (Linux/FreeBSD/etc) support has been tested on Ubuntu (x64). Linux Wayland support is also available. Bug report(s) for other OSes/CPUs are welcome! Notice: That after 0.13 Redox hasn't been updated and some work is required to get that working again. PR are welcome.

Build instructions

On Linux you may need to install these dependencies first:

sudo apt install libxkbcommon-dev libwayland-cursor0 libwayland-dev
cargo build
cargo run --example noise

This will run the noise example
