nit: looks like the next few comment modifications are accidental.

oops, one of my many regex replacements must have gone sideways!

…s buffer operations
…PassTimestampWrites usable with DynQuerySet
collateral: ComputePass uses DynCommandEncoder during recording
bindgroup fixup
…ffects from there leading to boxing of almost all hal resources
gfx_select macros are empty husks now that are waiting to be removed

wgpu-halDynDevice& friends #6098wgpu-core#6099gfx_select, remove compute/render pass indirections #6100Description
This is where the magic happens!
Almost all interaction of
wgpu-halinwgpu-coreuse now the previously introducedDynbackend abstraction.To achieve this, all hal resources are allocated as
Box<dyn hal::DynResource>(with more concrete types for safety & easy of use).Since hal resource are no longer distinguish type,
Hubscollapses to just a singleHub.AnyDeviceis no longer needed since every device is just aBox<dyn hal::DynDevice>Since
wgpu-coretypes are extremely intertwined (most of them have anArc<Device>) this happens in very few commits. However, I split out a few rough iterations with two major "unravelings": first boxing & dyn passing, then hub simplification & actual generic removal.In order to not have this PR spill into
wgpu,gfx_selecthas been stripped down to pass-through, it will be removed entirely in Part 3.Testing
