Struct InFlightDma 

pub struct InFlightDma { /* private fields */ }

DMA backing currently owned by a hardware request.

Dropping this object intentionally leaks the backing as a last-resort quarantine: safe callers must not observe memory reuse while hardware could still be accessing it.

Implementations

impl InFlightDma

pub fn len(&self) -> NonZeroUsize

pub fn direction(&self) -> DmaDirection

pub fn domain_id(&self) -> DmaDomainId

pub fn cpu_ptr(&self) -> NonNull<u8>

pub fn dma_addr(&self) -> DmaAddr

pub fn segment(&self) -> DmaSegment

pub unsafe fn complete_after_quiesce(self) -> CompletedDma

Safety

The caller must have stopped DMA bus-master access and any command/data engine that can touch this exact in-flight backing.

pub fn quarantine(self) -> QuarantinedDma
