Trait Implementations

impl<'d, T: BasicInstance> BufRead for BufferedUart<'d, T>

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

Return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(&mut self, amt: usize)

Tell this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to fill_buf.

impl<'d, T: BasicInstance> ErrorType for BufferedUart<'d, T>

type Error = Error

Error type of all the IO operations on this type.

impl<'d, T: BasicInstance> ErrorType for BufferedUart<'d, T>

type Error = Error

Error type

impl<'d, T: BasicInstance> Read for BufferedUart<'d, T>

fn read(&mut self) -> Result<u8, Error<Self::Error>>

Reads a single word from the serial interface

impl<'d, T: BasicInstance> Read for BufferedUart<'d, T>

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

Read some bytes from this source into the specified buffer, returning how many bytes were read.

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

Read the exact number of bytes required to fill buf.

impl<'d, T: BasicInstance> Read for BufferedUart<'d, T>

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

Read some bytes from this source into the specified buffer, returning how many bytes were read.

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

Read the exact number of bytes required to fill buf.

impl<'d, T: BasicInstance> SetConfig for BufferedUart<'d, T>

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>

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, T: BasicInstance> Write for BufferedUart<'d, T>

fn write(&mut self, char: u8) -> Result<(), Self::Error>
