Implementations

impl FrameBufferInfo

pub fn memory_size(&self) -> usize

The size of the memory buffer required to hold the framebuffer

pub fn get_arr_pos(&self, pos: (usize, usize)) -> Option<usize>

pub fn pixel_mem<'a>( &self, memory: &'a [u8], pos: (usize, usize) ) -> Option<&'a [u8]>

Get the pixel slice at a given position (read-only)

pub fn pixel_mem_mut<'a>( &self, memory: &'a mut [u8], pos: (usize, usize) ) -> Option<&'a mut [u8]>

Get the pixel slice at a given position
