This is a meta issue to describe the long-ish term vision for wgpu-core's resource management and track the steps towards it.

Registries and IDs

Internally, all wgpu-core resources are stored behind Arcs. Externally, they are exposed as non-clonable structs containing an ID which conceptually corresponds to a single reference to the Arc of a resource.

The goal

Instead of having wgpu public types wrap a non-clonabe ID, we would like them to wrap the Arc to the internal resource directly (and be clonable).

TODO

• Resolve cycles in wgpu-core using weak references #5120
• Remove remaining internal use of the IDs.
• Make wgpu-core less generic (brainstorm) #5124
• Rewrite the record-reply functionality Add back support for tracing (trace feature) to wgpu #5974
• Move ErrorSink into wgpu-core #8911
• (Firefox): Move the wgpu-core part of command recording out of the content process
• Move logic present in the Global's methods into methods on wgpu-core objects
• (Firefox): Stop providing the IDs during resource creation and do ID mapping in the gecko-side bindings.
• Remove the registries
