Struct CameraTransfer

pub struct CameraTransfer<'d, BUF: DmaRxBuffer> { /* private fields */ }

Available on crate feature unstable only.

Represents an ongoing (or potentially stopped) transfer from the Camera to a DMA buffer.

Implementations

impl<'d, BUF: DmaRxBuffer> CameraTransfer<'d, BUF>

pub fn is_done(&self) -> bool

Returns true when Self::wait will not block.

pub fn stop(self) -> (Camera<'d>, BUF)

Stops this transfer on the spot and returns the peripheral and buffer.

pub fn wait(self) -> (Result<(), DmaError>, Camera<'d>, BUF)

Waits for the transfer to stop and returns the peripheral and buffer.

Note: The camera doesn’t really “finish” its transfer, so what you’re really waiting for here is a DMA Error. You typically just want to call Self::stop once you have the data you need.

Trait Implementations

impl<BUF: DmaRxBuffer> Deref for CameraTransfer<'_, BUF>

type Target = <BUF as DmaRxBuffer>::View

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<BUF: DmaRxBuffer> DerefMut for CameraTransfer<'_, BUF>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<BUF: DmaRxBuffer> Drop for CameraTransfer<'_, BUF>

fn drop(&mut self)

Executes the destructor for this type.
