Struct libcamera::framebuffer_map::MemoryMappedFrameBuffer

pub struct MemoryMappedFrameBuffer<T: AsFrameBuffer> { /* private fields */ }

FrameBuffer wrapper, which exposes internal file descriptors as memory mapped [&u8] plane slices.

Implementations

impl<T: AsFrameBuffer> MemoryMappedFrameBuffer<T>

pub fn new(fb: T) -> Result<Self, MemoryMappedFrameBufferError>

Memory map framebuffer, which implements AsFrameBuffer.

This might fail if framebuffer has invalid plane sizes/offsets or if [libc::mmap] fails itself.

pub fn data(&self) -> Vec<&[u8]>

Returns data slice for each plane within the framebuffer.

Trait Implementations

impl<T: AsFrameBuffer> AsFrameBuffer for MemoryMappedFrameBuffer<T>

unsafe fn ptr(&self) -> NonNull<libcamera_framebuffer_t>

Returns raw framebuffer used by libcamera.

fn metadata(&self) -> Option<Immutable<FrameMetadataRef<'_>>>

Returns framebuffer metadata information.

fn planes(&self) -> Immutable<FrameBufferPlanesRef<'_>>

Provides access to framebuffer data by exposing file descriptors, offsets and lengths of the planes.

impl<T: AsFrameBuffer> Drop for MemoryMappedFrameBuffer<T>

fn drop(&mut self)

Executes the destructor for this type.
