Trait 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so 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)
