Custom Materials with Atomic Counter

[DasLixou]

What problem does this solve or what need does it fill?

After #6988 I've questioned myself if it would be also possible to make custom materials use atomic counter for their AsBindGroup, instead of TypeUUID.

What solution would you like?

Make the AsBindGroup derive also increasing the atomic counter, so that lines like

bevy/examples/shader/shader_material.rs

Line 57 in b6066c3

#[uuid = "f690fdae-d598-45ab-8225-97e2a3f056e0"]

don't need to exist anymore.

That line is for the TypeUuid derive. It's required to support using it as an asset. The use case is entirely different and definitely needs a stable independent unique ID that is the same across compilations and executions of the same binary. I don't think we can get rid of that without the stable type name as a replacement for TypeUuid.

Oh I See.. should this be closed?

Probably should. I don't think this issue is actionable. Feel free to reopen if there is something tangible we could do to improve our use of UUIDs here.
