Struct I2sWriteDmaTransferAsync

Source 
pub struct I2sWriteDmaTransferAsync<'d, BUFFER> { /* private fields */ }
Available on crate feature unstable only.
Expand description

An in-progress async circular DMA write transfer.

Implementations§

Source§

impl<BUFFER> I2sWriteDmaTransferAsync<'_, BUFFER>

Source

pub async fn available(&mut self) -> Result<usize, Error>

How many bytes can be pushed into the DMA transaction. Will wait for more than 0 bytes available.

Source

pub async fn push(&mut self, data: &[u8]) -> Result<usize, Error>

Push bytes into the DMA transaction.

Source

pub async fn push_with( &mut self, f: impl FnOnce(&mut [u8]) -> usize, ) -> Result<usize, Error>

Push bytes into the DMA buffer via the given closure. The closure must return the actual number of bytes written. The closure might get called with a slice which is smaller than the total available buffer. Only useful for circular DMA transfers
