1//! Traits for accessing I/O ports.

3/// A helper trait that implements the read port operation.
4///
5/// On x86, I/O ports operate on either `u8` (via `inb`/`outb`), `u16` (via `inw`/`outw`),
6/// or `u32` (via `inl`/`outl`). Therefore this trait is implemented for exactly these types.
7pub trait PortRead {
8    /// Reads a `Self` value from the given port.
9    ///
10    /// ## Safety
11    ///
12    /// This function is unsafe because the I/O port could have side effects that violate memory
13    /// safety.
14    unsafe fn read_from_port(port: u16) -> Self;
15}

17/// A helper trait that implements the write port operation.
