fn master_write(&mut self, addr: u8, bytes: &[u8]) -> Result<(), Error>

Send data bytes from the bytes array to a target slave with the address addr

fn master_read(&mut self, addr: u8, buffer: &mut [u8]) -> Result<(), Error>

Read bytes from a target slave with the address addr The number of read bytes is deterimed by the size of the buffer argument

fn master_write_read(
    &mut self,
    addr: u8,
    bytes: &[u8],
    buffer: &mut [u8]
) -> Result<(), Error>
