Struct PortGeneric

pub struct PortGeneric<T, A> { /* private fields */ }

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>

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: PortRead, A: PortReadAccess> PortGeneric<T, A>

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: PortWrite, A: PortWriteAccess> PortGeneric<T, A>

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.

Trait Implementations

impl<T, A> Clone for PortGeneric<T, A>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, A: PortAccess> Debug for PortGeneric<T, A>

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

Formats the value using the given formatter.

impl<T, A> PartialEq for PortGeneric<T, A>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
