Struct IoMem 

pub struct IoMem<'a, const SIZE: usize = 0> { /* private fields */ }

A generic memory-mapped IO region.

Accesses to the underlying region is checked either at compile time, if the region’s size is known at that point, or at runtime otherwise.

Invariants

IoMem always holds an MmioRaw instance that holds a valid pointer to the start of the I/O memory mapped region.

Implementations

impl<'a, const SIZE: usize> IoMem<'a, SIZE>

pub fn into_devres(self) -> Result<DevresIoMem<SIZE>>

Consume the IoMem and register it as a device-managed resource.

The returned DevresIoMem can outlive the original borrow and be stored in driver data. Access to the I/O memory is revoked automatically when the device is unbound.

Trait Implementations

impl<const SIZE: usize> CovariantForLt for IoMem<'static, SIZE>

fn cast_ref<'r, 'short: 'r, 'long: 'short>( long: &'r Self::Of<'long>, ) -> &'r Self::Of<'short>

Cast a reference to a shorter lifetime.

impl<const SIZE: usize> Drop for IoMem<'_, SIZE>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<const SIZE: usize> ForLt for IoMem<'static, SIZE>

type Of<'a> = IoMem<'a, SIZE>

The type parameterized by the lifetime.

impl<'a, const SIZE: usize> IoBase<'a> for &'a IoMem<'_, SIZE>

type Backend = MmioBackend

Type that defines all I/O operations.

type Target = Region<SIZE>

Type of this I/O region. For untyped regions, Region can be used.

fn as_view(self) -> Mmio<'a, Self::Target>

Return a view that covers the full region.
