Trait PortOps

pub trait PortOps {
    // Required methods
    unsafe fn read8(&self, port: u16) -> u8;
    unsafe fn read16(&self, port: u16) -> u16;
    unsafe fn read32(&self, port: u16) -> u32;
    unsafe fn write8(&self, port: u16, val: u8);
    unsafe fn write16(&self, port: u16, val: u16);
    unsafe fn write32(&self, port: u16, val: u32);
}

A trait defining port I/O operations.

All port I/O operations are parametric over this trait. This allows operating systems to use this crate without modifications, by suitably instantiating this trait with their own primitives.

Required Methods

unsafe fn read8(&self, port: u16) -> u8

unsafe fn read16(&self, port: u16) -> u16

unsafe fn read32(&self, port: u16) -> u32

unsafe fn write8(&self, port: u16, val: u8)

unsafe fn write16(&self, port: u16, val: u16)

unsafe fn write32(&self, port: u16, val: u32)
