Struct cpuio::Port [−] [src]

pub struct Port<T: InOut> {
    // some fields omitted
}

An I/O port over an arbitrary type supporting the InOut interface.

Methods

impl<T: InOut> Port<T>
[src]

const unsafe fn new(port: u16) -> Port<T>

Create a new I/O port. This is marked unsafe because it's the responsibility of the caller to make that we're pointed at a valid port address, and to make sure that returned port is used correctly.

This is marked as const so that you can define ports with known addresses at compile time.

fn read(&mut self) -> T

Read data from the port. This is nominally safe, because you shouldn't be able to get hold of a port object unless somebody thinks it's safe to give you one.

fn write(&mut self, value: T)

Write data to the port.
