Struct Reader 

pub struct Reader<D, P>
where
    D: UartDevice,
    P: ValidUartPinout<D>,
{ /* private fields */ }

Half of an UartPeripheral that is only capable of reading. Obtained by calling UartPeripheral::split()

Implementations

impl<D, P> Reader<D, P>

where D: UartDevice, P: ValidUartPinout<D>,

pub fn read_raw<'b>( &self, buffer: &'b mut [u8], ) -> Result<usize, Error<ReadError<'b>>>

Reads bytes from the UART. This function reads as long as it can. As soon that the FIFO is empty, if :

• 0 bytes were read, a WouldBlock Error is returned
• some bytes were read, it is deemed to be a success

Upon success, it will return how many bytes were read.

pub fn read_full_blocking(&self, buffer: &mut [u8]) -> Result<(), ReadErrorType>

Reads bytes from the UART. This function blocks until the full buffer has been received.

pub fn enable_rx_interrupt(&mut self)

Enables the Receive Interrupt.

The relevant UARTx IRQ will fire when there is data in the receive register.

pub fn disable_rx_interrupt(&mut self)

Disables the Receive Interrupt.
