Struct WaitTransfer 

pub struct WaitTransfer<FB>
where
    FB: DMACapableFrameBufferBackend<Color = Rgb565>,
{ /* private fields */ }

Reference AsyncDmaTransfer token backed by a CompletionSlot.

Implementations

impl<FB> WaitTransfer<FB>

where FB: DMACapableFrameBufferBackend<Color = Rgb565>,

pub fn new( framebuffer: FrameBuf<Rgb565, FB>, completion: &'static CompletionSlot, ) -> Self

Build a transfer token; completion must outlive all in-flight DMA ops.

pub const fn completion(&self) -> &'static CompletionSlot

The completion slot wired to this transfer (for ISR handlers).

Trait Implementations

impl<FB> AsyncDmaTransfer for WaitTransfer<FB>

where FB: DMACapableFrameBufferBackend<Color = Rgb565>,

type WaitFuture = WaitTransferFuture<FB>

The future type returned by wait_async.

fn wait_async(self) -> Self::WaitFuture

Return a future that resolves to the framebuffer once the DMA transfer completes.

impl<FB> DmaTransfer for WaitTransfer<FB>

where FB: DMACapableFrameBufferBackend<Color = Rgb565>,

type Buffer = FrameBuf<Rgb565, FB>

The buffer type that is returned when the transfer completes.

fn is_done(&self) -> bool

Returns true if the DMA hardware has finished the transfer.

fn wait(self) -> Self::Buffer

Block until the transfer is complete and return the framebuffer.
