m3vict[m]: Now I would like to create a further library code using those commands and I no longer care if it is u8 and u16. How can I minimize code duplication?

```
impl<SPI, Word> Qca7000<SPI, Word>
where
    SPI: SpiDevice<Word>,
    Word: u8 || u16,
{
    fn do_complex_stuff(&mut self){
        self.write_command(/*my command */);
    }
}
```
