Struct LinkedListTransfer

pub struct LinkedListTransfer<'a, const ITEM_COUNT: usize> { /* private fields */ }

Linked-list DMA transfer.

Implementations

impl<'a, const ITEM_COUNT: usize> LinkedListTransfer<'a, ITEM_COUNT>

pub unsafe fn new_linked_list<const N: usize>( channel: Peri<'a, impl Channel>, table: Table<ITEM_COUNT>, options: TransferOptions, ) -> Self

Create a new linked-list transfer.

pub fn request_pause(&mut self)

Request the transfer to pause, keeping the existing configuration for this channel.

To resume the transfer, call request_resume again. This doesn’t immediately stop the transfer, you have to wait until is_running returns false.

pub fn request_resume(&mut self)

Request the transfer to resume after having been paused.

pub fn request_reset(&mut self)

Request the DMA to reset.

The configuration for this channel will not be preserved. If you need to restart the transfer at a later point with the same configuration, see request_pause instead.

pub fn is_running(&mut self) -> bool

Return whether this transfer is still running.

If this returns false, it can be because either the transfer finished, or it was requested to stop early with request_pause.

pub fn get_remaining_transfers(&self) -> u16

Gets the total remaining transfers for the channel Note: this will be zero for transfers that completed without cancellation.

pub fn blocking_wait(self)

Blocking wait until the transfer finishes.

Trait Implementations

impl<'a, const ITEM_COUNT: usize> Drop for LinkedListTransfer<'a, ITEM_COUNT>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, const ITEM_COUNT: usize> Future for LinkedListTransfer<'a, ITEM_COUNT>

type Output = ()

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
