Struct PresentedFrame 

pub struct PresentedFrame { /* private fields */ }

A snapshot of a frame that has been presented by an app.

Returned by Rgb565FrameDisplay::active_frame. The display task should compare token values to detect when a new frame is available.

Implementations

impl PresentedFrame

pub fn width(&self) -> u16

Width of the presented frame in pixels.

pub fn height(&self) -> u16

Height of the presented frame in pixels.

pub fn len(&self) -> usize

Total number of pixels (width * height).

pub fn is_empty(&self) -> bool

Returns true if the frame has zero pixels.

pub fn with_pixels<R>(&self, f: impl FnOnce(&[Rgb565Pixel]) -> R) -> R

Access the pixel slice of the frame for rendering.

pub fn token(&self) -> u64

Monotonically changing token that changes when the app presents a new revision.

The upper 32 bits encode the frame ID; the lower 32 bits encode the revision counter.
