Trait Write

pub trait Write<Word = u8>: ErrorType
where
    Word: Copy,
{
    // Required methods
    fn write(&mut self, word: Word) -> Result<(), Error<Self::Error>>;
    fn flush(&mut self) -> Result<(), Error<Self::Error>>;
}

Write half of a serial interface.

Required Methods

fn write(&mut self, word: Word) -> Result<(), Error<Self::Error>>

Writes a single word to the serial interface.

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

Ensures that none of the previously written words are still buffered.

Trait Implementations

impl<Word, Error> Write for dyn Write<Word, Error = Error> + '_

where Error: Error, Word: Copy + From<u8>,

Implementation of core::fmt::Write for the HAL’s serial::Write.

TODO write example of usage

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

Writes a string slice 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.

Implementations on Foreign Types

impl<T, Word> Write<Word> for &mut T

where T: Write<Word> + ?Sized, Word: Copy,

fn write( &mut self, word: Word, ) -> Result<(), Error<<&mut T as ErrorType>::Error>>

fn flush(&mut self) -> Result<(), Error<<&mut T as ErrorType>::Error>>
