Trait ostd::arch::x86::device::io_port::PortWrite

pub trait PortWrite {
    // Required method
    unsafe fn write_to_port(port: u16, value: Self);
}

A helper trait that implements the write port operation.

On x86, I/O ports operate on either u8 (via inb/outb), u16 (via inw/outw), or u32 (via inl/outl). Therefore this trait is implemented for exactly these types.

Required Methods

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

Writes a Self value to the given port.

Safety

This function is unsafe because the I/O port could have side effects that violate memory safety.

Object Safety

This trait is not object safe.

Implementations on Foreign Types

impl PortWrite for u8

unsafe fn write_to_port(port: u16, value: u8)

impl PortWrite for u16

unsafe fn write_to_port(port: u16, value: u16)

impl PortWrite for u32

unsafe fn write_to_port(port: u16, value: u32)
