Struct PortGeneric 

pub struct PortGeneric<T, A> {
    port: u16,
    phantom: PhantomData<(T, A)>,
}

An I/O port.

The port reads or writes values of type T and has read/write access specified by A.

Use the provided marker types or aliases to get a port type with the access you need:

• PortGeneric<T, ReadWriteAccess> -> Port<T>
• PortGeneric<T, ReadOnlyAccess> -> PortReadOnly<T>
• PortGeneric<T, WriteOnlyAccess> -> PortWriteOnly<T>

Fields

port: u16

phantom: PhantomData<(T, A)>

Implementations

impl<T, A> PortGeneric<T, A>

pub const fn new(port: u16) -> PortGeneric<T, A>

Creates an I/O port with the given port number.

impl<T, A> PortGeneric<T, A>

where T: PortRead, A: PortReadAccess,

pub unsafe fn read(&mut self) -> T

Reads from the port.

Safety

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

impl<T, A> PortGeneric<T, A>

where T: PortWrite, A: PortWriteAccess,

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

Writes to the port.

Safety

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