Trait knurling_traits::serial::Serial

pub trait Serial {
    fn read_bytes(&mut self, output: &mut [u8]) -> Result<usize, ()>;
    fn write_bytes(&mut self, bytes: &[u8]) -> Result<usize, ()>;
}

A trait to define Serial (UART) port behavior

Blocking vs. Non-blocking behavior is not defined for this trait.

Required Methods

fn read_bytes(&mut self, output: &mut [u8]) -> Result<usize, ()>

Attempt to read up to output.len() bytes. Number of bytes read is returned. If an error is returned, no bytes are assumed to be read

fn write_bytes(&mut self, bytes: &[u8]) -> Result<usize, ()>

Attempt to write all given bytes. Number of bytes written is returned. If an error is returned, no bytes are assumed to be written
