Struct esp32c3_hal::i2s::I2sWriteDmaTransfer

pub struct I2sWriteDmaTransfer<'d, T, P, CH, BUFFER>where
    T: RegisterAccess,
    CH: ChannelTypes,
    P: I2sTxPins,{ /* private fields */ }

An in-progress DMA write transfer.

Implementations

impl<'d, T, P, CH, BUFFER> I2sWriteDmaTransfer<'d, T, P, CH, BUFFER>where T: RegisterAccess, CH: ChannelTypes, P: I2sTxPins,

pub fn available(&mut self) -> usize

Amount of bytes which can be pushed. Only useful for circular DMA transfers

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

Push bytes into the DMA buffer. Only useful for circular DMA transfers

Trait Implementations

impl<'d, T, P, CH, BUFFER> DmaTransfer<BUFFER, I2sTx<'d, T, P, CH>> for I2sWriteDmaTransfer<'d, T, P, CH, BUFFER>where T: RegisterAccess, CH: ChannelTypes, P: I2sTxPins,

fn wait( self ) -> Result<(BUFFER, I2sTx<'d, T, P, CH>), (DmaError, BUFFER, I2sTx<'d, T, P, CH>)>

Wait for the DMA transfer to complete and return the buffers and the I2sTx instance.

fn is_done(&self) -> bool

Check if the DMA transfer is complete

impl<'d, T, P, CH, BUFFER> Drop for I2sWriteDmaTransfer<'d, T, P, CH, BUFFER>where T: RegisterAccess, CH: ChannelTypes, P: I2sTxPins,

fn drop(&mut self)

Executes the destructor for this type.
