Trait Implementations

impl FrameBuffer for SimpleFrameBuffer

fn get_width(&self) -> usize

fn get_height(&self) -> usize

unsafe fn get_unchecked(&self, x: usize, y: usize) -> u32

Safety

fn set(&self, x: usize, y: usize, rgba: u32)

fn set_multi_from_start_index( &self, starting_index: usize, pixels: &[u8], ) -> usize

Returns the number of pixels copied

fn as_bytes(&self) -> &[u8]

fn as_pixels(&self) -> &[u32]

fn get_size(&self) -> usize

fn get(&self, x: usize, y: usize) -> Option<u32>

fn set_multi( &self, start_x: usize, start_y: usize, pixels: &[u8], ) -> (usize, usize)

We can not take an &[u32] for the pixel here, as std::slice::from_raw_parts requires the data to be aligned. As the data already is stored in a buffer we can not guarantee it’s correctly aligned, so let’s just treat the pixels as raw bytes.
