Trait Implementations

impl<'a, DMA: StreamServer<'a>> Configure for Usart<'a, DMA>

fn configure(&self, params: Parameters) -> Result<(), ErrorCode>

Returns Ok(()), or

impl<'a, DMA: StreamServer<'a>> DeferredCallClient for Usart<'a, DMA>

fn register(&'static self)

fn handle_deferred_call(&self)

impl<'a, DMA: StreamServer<'a>> Receive<'a> for Usart<'a, DMA>

fn set_receive_client(&self, client: &'a dyn ReceiveClient)

Set the receive client, which will he called when reads complete.

fn receive_buffer( &self, rx_buffer: &'static mut [u8], rx_len: usize ) -> Result<(), (ErrorCode, &'static mut [u8])>

Receive rx_len bytes into rx_buffer, making a callback to the ReceiveClient when complete. If the Result<(), ErrorCode> of receive_buffer’s return is Ok(()), the struct will issue a received_buffer callback in the future. If the value of the Result<(), ErrorCode> is Err(), then the rx_buffer argument is returned in the Err(). Valid ErrorCode values are:

fn receive_word(&self) -> Result<(), ErrorCode>

Receive a single word of data. The word length is determined by the UART configuration: it can be 6, 7, 8, or 9 bits long. If the Result<(), ErrorCode> is Ok(()), on completion, received_word will be called on the ReceiveClient. Other valid ErrorCode values are:

fn receive_abort(&self) -> Result<(), ErrorCode>

Abort any ongoing receive transfers and return what is in the receive buffer with the receive_complete callback. If Ok(()) is returned, there will be no callback (no call to receive was outstanding). If there was a receive outstanding, which is cancelled successfully then BUSY will be returned and there will be a callback with a Result<(), ErrorCode> of CANCEL. If there was a reception outstanding, which is not cancelled successfully, then FAIL will be returned and there will be a later callback.

impl<'a> StreamClient<'a, Dma1<'a>> for Usart<'a, Dma1<'a>>

fn transfer_done(&self, pid: Dma1Peripheral)

impl<'a> StreamClient<'a, Dma2<'a>> for Usart<'a, Dma2<'a>>

fn transfer_done(&self, pid: Dma2Peripheral)

impl<'a, DMA: StreamServer<'a>> Transmit<'a> for Usart<'a, DMA>

fn set_transmit_client(&self, client: &'a dyn TransmitClient)

Set the transmit client, which will be called when transmissions complete.

fn transmit_buffer( &self, tx_data: &'static mut [u8], tx_len: usize ) -> Result<(), (ErrorCode, &'static mut [u8])>

Transmit a buffer of data. On completion, transmitted_buffer in the TransmitClient will be called. If the Result<(), ErrorCode> returned by transmit is an Ok(()), the struct will issue a transmitted_buffer callback in the future. If the value of the Result<(), ErrorCode> is Err(), then the tx_bufferargument is returned in theErr(), along with the ErrorCode. Valid ErrorCode` values are:

fn transmit_word(&self, _word: u32) -> Result<(), ErrorCode>

Transmit a single word of data asynchronously. The word length is determined by the UART configuration: it can be 6, 7, 8, or 9 bits long. If the Result<(), ErrorCode> is Ok(()), on completion, transmitted_word will be called on the TransmitClient. Other valid Result<(), ErrorCode> values are:

fn transmit_abort(&self) -> Result<(), ErrorCode>

Abort an outstanding call to transmit_word or transmit_buffer. The return code indicates whether the call has fully terminated or there will be a callback. Cancelled calls to transmit_buffer MUST always make a callback, to return the passed buffer back to the caller.
