Trait Draw 

pub trait Draw {
    // Provided methods
    fn draw_buffer(
        &mut self,
        _screen_buf: &[u8],
        _screen_width: usize,
        _screen_height: usize,
    ) { ... }
    fn clear_screen(&mut self) { ... }
}

Implement this trait on a type and use it to draw to or clear the screen.

Provided Methods

fn draw_buffer( &mut self, _screen_buf: &[u8], _screen_width: usize, _screen_height: usize, )

This function will be called each time the interpreter requests to draw to the screen. The buffer you are given is just a flat list, but you are given the width and height so you can make it square yourself.

fn clear_screen(&mut self)

Clear screen will simply be called when the interpreter calls the clear screen instruction.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
