RenderPass
make it difficult to use. #1453Part of a series towards lifetime removal on compute passes:
wgpu::ComputePass
) #5432wgpu::ComputePass
methods #5570ComputePass
to its parent command encoder #5620Description
ComputePass
had a static lifetime dependency to its parent encoder. This PR removes this (ComputePass<'a>
->ComputePass
) by havingComputePass
own an Arc to its parent encoder. A side-effect of this is thatComputePass
creation can now fail in theory (if an invalid id is passed or commandbuffer allocation fails for some reason).Another wide reaching side effect is that command encoders can now be in a
Locked
state. (via WebGPU spec) any operation on a locked command encoder fails and makes the encoder invalid.The last remaining lifetime dependency to resolve on
ComputePass
after this PR is inComputePassTimestampWrites<'a>
: We currently don't bump the reference count on the referencedQuerySet
. This is in fact more of a pre-existing bug since destroying a QuerySet after recording it in a ComputePass and before closing the pass already causes issues!Testing
