Provided Methods§

Source

fn console_read(&self, _buf: &mut [u8], _timeout: Duration) -> Result<usize>

Reads data from the UART to print to the console (used when this UART is the console device).

Source

fn console_write(&self, _buf: &[u8]) -> Result<()>

Writes console input data to the UART (used when this UART is the console device).

Source

fn set_break(&self, _enable: bool) -> Result<()>

Source

fn get_tx_ready_pin(&self) -> Result<Option<&Rc<dyn GpioPin>>>

Query if TX-ready pin non-polling mode is supported.

Source

fn supports_nonblocking_read(&self) -> Result<bool>

Query if nonblocking mio mode is supported.

Source

fn register_nonblocking_read( &self, _registry: &Registry, _token: Token, ) -> Result<()>

Switch this Uart instance into nonblocking mio mode. Going forward, read() should only be called after mio::poll() has indicated that the given Token is ready.

Source

fn nonblocking_help(&self) -> Result<Rc<dyn NonblockingHelp>>

Get the same single NonblockingHelp object as from top level Transport.nonblocking_help().
