Struct rstubs::arch::io::Port

pub struct Port<T: PortValue>(pub u16, PhantomData<T>);

An IO port that can read/write register values.

This class is generic and supports any type that implements PortValue and can be converted into a 1, 2 or 4 byte integer.

Tuple Fields

0: u16

1: PhantomData<T>
