Trait Write 

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

Write half of a serial interface.

Required Methods

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

Writes a single word to the serial interface.

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

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

Trait Implementations

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

where 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

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<T: Write<Word> + ?Sized, Word: Copy> Write<Word> for &mut T

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