 rust_minifb (Mini FrameBuffer) is a small cross platform library written in [Rust](https://www.rust-lang.org) and that makes it easy to render (32-bit) pixels in a window. An example is the best way to show how it works:
 
+Usage
+-----

+```toml

+minifb = "0.2.1"

+Example

 ```rust
 extern crate minifb;
 
-use minifb::*;

 const WIDTH: usize = 640;
