yeah..: ```
pub struct OW<T, TI, TO> {
    pin: T,
    _ti: PhantomData<TI>,
    _to: PhantomData<TO>,
}

impl<T, TI, TO, E> OW<T, TI, TO>
where
    TI: InputPin<Error = E> + IoPin<TI, TO>,
    TO: OutputPin<Error = E> + IoPin<TI, TO>,
    T: IoPin<TI, TO>,
{
    pub fn new() -> Self {
        todo!()
    }
}


```
