Struct ExclusiveIoMem 

Source 
pub struct ExclusiveIoMem<'a, const SIZE: usize> { /* private fields */ }
Expand description

An exclusive memory-mapped IO region.

§Invariants

Implementations§

Source§

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

Source

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

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

The returned DevresExclusiveIoMem 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.

Source§

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

Cast a reference to a shorter lifetime.
Source§

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

Source§

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

The type parameterized by the lifetime.
Source§

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

Source§

type Backend = MmioBackend

Type that defines all I/O operations.
Source§

type Target = Region<SIZE>

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

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

Return a view that covers the full region.
