There was a problem hiding this comment.
G2G once spec is clear and web_sys is ready.

Updated the PR to align with the terminology that made it into the spec. I will get to the web-sys update soon. |

@nical @cwfitzgerald I think web-sys 0.3.60 should include Nical's update. |

This needs #2954 |
Looks like web-sys makes non-breaking version bumps when there are breaking changes in unstable APIs so sticking to specific versions should avoid unnecessary breakage.

Description
The max binding index is reduced to 640 to avoid issues with wgpu's vulkan backend, for which binding indices map directly to the indices in vkCreateDescriptorSetLayout.
640 is the new default limit advertised by the spec, but technically non-vukan backends rename all of the bindings so they aren't affected by the same issue and can continue using 65535 (the previous limit) if requested.
This PR also exposes the limit in
Limits.We don't have to merge this right away since the change has not made it into the WebGPU spec yet.
