Struct FrontBuffer 

pub struct FrontBuffer<'a> { /* private fields */ }

Shared read-only view of a framebuffer currently handed to the display scan-out engine (LTDC CFBAR).

Deliberately exposes no &mut accessors: the scan-out path reads these pixels at pixel-clock rate, so CPU writes would tear. Obtaining write access requires swapping this buffer out via Scanout::swap first.

Implementations

impl<'a> FrontBuffer<'a>

pub fn wrap(fb: &'a FrameBuffer) -> Self

Wrap a shared reference to a FrameBuffer.

pub fn framebuffer(&self) -> &FrameBuffer

Underlying FrameBuffer.

pub fn addr(&self) -> PhysAddr

Physical base address.

pub fn dma_addr(&self) -> DmaAddr

DMA bus address (for writing into LTDC CFBAR).

pub fn width(&self) -> u32

Width in pixels.

pub fn height(&self) -> u32

Height in pixels.

pub fn stride_bytes(&self) -> u32

Row stride in bytes.

pub fn format(&self) -> PixelFmt

Pixel format.
