Expand description

Write half of a serial interface.

Required Methods§

source

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

Writes a single word to the serial interface.

source

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

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