Required Methods

fn width(&self) -> usize

Return the width of the framebuffer in pixels.

fn height(&self) -> usize

Returns the height of the framebuffer in pixels.

fn set_pixel(&mut self, x: usize, y: usize, color: RgbColor) -> &mut Self

Set the pixel at position (x, y) to the provided color.

fn scroll_vert(&mut self, px: isize) -> &mut Self

Provided Methods

fn line_horiz(&mut self, y: usize, len: usize, color: RgbColor) -> &mut Self

Draw a horizontal line of length len at height y.

By default, this method calls set_pixel in a loop. This works, but implementations can almost certainly provide a more optimal implementation, and are thus encouraged to override this method.

fn line_vert(&mut self, x: usize, len: usize, color: RgbColor) -> &mut Self

Draw a vertical line of length len at column y.

By default, this method calls set_pixel in a loop. This works, but implementations can almost certainly provide a more optimal implementation, and are thus encouraged to override this method.

fn fill_row(&mut self, y: usize, color: RgbColor) -> &mut Self

fn fill_col(&mut self, x: usize, color: RgbColor) -> &mut Self

fn fill(&mut self, color: RgbColor) -> &mut Self

Fill the entire framebuffer with the provided color.

By default, this method calls set_pixel in a loop. This works, but implementations can almost certainly provide a more optimal implementation, and are thus encouraged to override this method.

fn clear(&mut self) -> &mut Self

Clear the entire framebuffer.

By default, this method calls set_pixel in a loop. This works, but implementations can almost certainly provide a more optimal implementation, and are thus encouraged to override this method.
