Implementations

impl Buffer

fn get_real_bounds(
    &self,
    framebuffer_width: u32,
    framebuffer_height: u32
) -> (u32, u32, u32, u32)

Returns the buffer's bounds within the given width/height, cropping as necessary.

Panics

Panics on overflow if top + height overflows.

fn width(&self) -> u32

Get the width of this buffer.

fn height(&self) -> u32

Get the height of this buffer.

pub fn get_buffer(&self) -> &[AtomicU32]

Gets the underlying framebuffer

pub fn get_px_offset(&self, x: usize, y: usize) -> usize

Gets the offset in memory of a pixel based on an x and y.

Panics

Panics if y >= self.height() or x >= self.width()

fn draw(&self)

Blit the buffer to the framebuffer.
