oa::Event

Cheap non-owning completion value shared by compute, image, video, capture, rendering, and training. It is a GPU dependency first and a host wait handle second. queue submission consumes it through private Runtime lowering; public callers wait only at a deliberate CPU boundary.

bool

bool oa::Event::isValid()

No public source comment is attached to this declaration.

Returns

bool

The declared return value.

oa::U32 oa::Event::queueFamily()

queue-family provenance is synchronization metadata, not a vulkan handle. A different family still requires an explicit exclusive-resource release/acquire ownership transfer in addition to an event dependency.

Returns

oa::U32

The declared return value.

oa::U64 oa::Event::value()

No public source comment is attached to this declaration.

Returns

oa::U64

The declared return value.

oa::Status oa::Event::wait(
	oa::U64 inTimeoutNs = UINT64_MAX
)

No public source comment is attached to this declaration.

Parameters

inTimeoutNs

oa::U64

Default: UINT64_MAX

Returns

oa::Status

The declared return value.
