Trait FrameBuffer 

pub trait FrameBuffer {
    // Required methods
    fn get_word_size(&self) -> WordSize;
    fn plane_count(&self) -> usize;
    fn plane_ptr_len(&self, plane_idx: usize) -> (*const u8, usize);
}

Trait for read-only framebuffers.

Required Methods

fn get_word_size(&self) -> WordSize

Returns the word size configuration for this framebuffer

fn plane_count(&self) -> usize

Returns the number of BCM bit-planes in this framebuffer.

Contiguous (threshold-based) framebuffers return 1 — the entire buffer is treated as a single plane. True bit-plane framebuffers return the number of planes (typically equal to the colour depth in bits).

fn plane_ptr_len(&self, plane_idx: usize) -> (*const u8, usize)

Returns a raw pointer and byte length for the given plane.

For a single-plane framebuffer (plane_count() == 1), plane_idx must be 0 and the returned span covers the whole DMA-ready buffer.

Panics

May panic if plane_idx >= plane_count().
