Trait Implementations

impl<Word, Error> Write for dyn Write<Word, Error = Error> + 'static where
    Word: From<u8>, 

fn write_str(&mut self, s: &str) -> Result<(), Error>

Writes a slice of bytes into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a [char] into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments) -> Result<(), Error>

Glue for usage of the [write!] macro with implementors of this trait.

Implementors

impl<USART> Write<u8> for Tx<USART> where
    USART: Deref<Target = RegisterBlock>, 

type Error = Void

fn flush(&mut self) -> Result<(), Error<<Tx<USART> as Write<u8>>::Error>>

Ensures that none of the previously written words are still buffered

fn write(
    &mut self,
    byte: u8
) -> Result<(), Error<<Tx<USART> as Write<u8>>::Error>>

Tries to write a byte to the uart Fails if the transmit buffer is full
