Struct BufferedUartTx 

pub struct BufferedUartTx<'d> { /* private fields */ }

Tx-only buffered UART

Created with BufferedUart::split

Implementations

impl<'d> BufferedUartTx<'d>

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

Write to the TX buffer, waiting until there is space for at least one byte.

Returns the number of bytes written, which is at least 1 if buf is not empty.

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

Wait until the TX buffer is empty and the last byte has been transmitted.

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

Write to the TX buffer, busy-waiting until there is space for at least one byte.

Returns the number of bytes written, which is at least 1 if buf is not empty.

pub fn blocking_flush(&mut self) -> Result<(), Error>

Busy-wait until the TX buffer is empty and the last byte has been transmitted.

pub fn write_ready(&mut self) -> Result<bool, Error>

Return whether the TX buffer has space, so that a write would not wait.

pub fn set_config(&mut self, config: &Config) -> Result<(), ConfigError>

Reconfigure the driver

pub fn send_break(&self)

Send break character

pub fn set_baudrate(&self, baudrate: u32) -> Result<(), ConfigError>

Set baudrate

Trait Implementations

impl<'d> Drop for BufferedUartTx<'d>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<'d> ErrorType for BufferedUartTx<'d>

type Error = Error

Error type of all the IO operations on this type.

impl<'d> SetConfig for BufferedUartTx<'d>

type Config = Config

The configuration type used by this driver.

type ConfigError = ConfigError

The error type that can occur if set_config fails.

fn set_config(&mut self, config: &Self::Config) -> Result<(), Self::ConfigError>

Set the configuration of the driver.

impl<'d> Write for BufferedUartTx<'d>

async fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

async fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.

impl<'d> Write for BufferedUartTx<'d>

fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, blocking until all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.

fn write_fmt( &mut self, fmt: Arguments<'_>, ) -> Result<(), WriteFmtError<Self::Error>>

Write a formatted string into this writer, returning any error encountered.

impl<'d> Write<u8> for BufferedUartTx<'d>

type Error = Error

The type of error that can occur when writing

fn bwrite_all(&mut self, buffer: &[u8]) -> Result<(), Self::Error>

Writes a slice, blocking until everything has been written

fn bflush(&mut self) -> Result<(), Self::Error>

Block until the serial interface has sent all buffered words

impl<'d> WriteReady for BufferedUartTx<'d>

fn write_ready(&mut self) -> Result<bool, Self::Error>

Get whether the writer is ready for immediately writing.
