Struct cpuio::Port

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

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

This version of Port has safe read and write functions, and it's appropriate for communicating with hardware that can't violate Rust's safety guarantees.

Methods

impl<T: InOut> Port<T>

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

Create a new I/O port.

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.

Trait Implementations

impl<T: Debug + InOut> Debug for Port<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
