Struct PixelBuffer

pub struct PixelBuffer { /* private fields */ }

Array of pixels resource that can be written to from the RenderSystem system.

use specs::prelude::*;
use specs_blit::PixelBuffer;

const WIDTH: usize = 800;
const HEIGHT: usize = 800;

// Setup the specs world
let mut world = World::new();

// Add the pixel buffer as a resource so it can be accessed from the RenderSystem later
world.insert(PixelBuffer::new(WIDTH, HEIGHT));
