pub struct PortWriteOnly<T: PortOut> { /* private fields */ }

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

Implementations

Create a new read-only I/O port.

pub const fn port_address(&self) -> u16

Returns the address of this port.

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