Struct port_io::Port

pub struct Port<T: PortIn + PortOut> { /* private fields */ }

A readable and writable I/O port over an arbitrary type supporting the InOut interface, which is only u8, u16, or u32.

Implementations

impl<T: PortIn + PortOut> Port<T>

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

Create a new I/O port.

pub const fn port_address(&self) -> u16

Returns the address of this port.

pub fn read(&self) -> T

Read data of size T from the port.

pub unsafe fn write(&self, value: T)

Write data of size T to the port. This is unsafe because writing to an arbitrary port may cause problems.

Trait Implementations

impl<T: Debug + PortIn + PortOut> Debug for Port<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
