Trait cpuio::InOut

pub trait InOut {
    unsafe fn port_in(port: u16) -> Self;
    unsafe fn port_out(port: u16, value: Self);
}

This trait is defined for any type which can be read or written over a port. The processor supports I/O with u8, u16 and u32. The functions in this trait are all unsafe because they can write to arbitrary ports.

Required methods

unsafe fn port_in(port: u16) -> Self

Read a value from the specified port.

unsafe fn port_out(port: u16, value: Self)

Write a value to the specified port.
