Struct Bar 

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

A PCI BAR to perform I/O-Operations on.

I/O backend assumes that the device is little-endian and will automatically convert from little-endian to CPU endianness.

Invariants

Bar always holds an IoRaw instance that holds a valid pointer to the start of the I/O memory mapped PCI BAR and its size.

Implementations

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

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

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

The returned DevresBar can outlive the original borrow and be stored in driver data. Access to the BAR is revoked automatically when the device is unbound.

Trait Implementations

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

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

The type parameterized by the lifetime.

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