spirv_headers don't follow semantic versioning so breakage like this is sort-of unavoidable without some changes to the policy of this project :-(

We've run into this before with #117

[Jasper-Bekkers]

For reference - required_capabilities and required_extensions got moved into Operand instead because there can be multiple capabilties or extensions required.

[kvark]

Wait, #117 was actually fixed, and sanity was restored. Are you saying that the current breakage is intended?

[Jasper-Bekkers]

In #117 a workaround got introduced to not break semver, however in this case I'm not sure we can (see previous comment).

[Jasper-Bekkers]

It's specifically this comment that explains why we're in this spot though I'm not a big fan (for obvious reasons).

That comment was made quite some time ago when we saw the first breakage. Things do change and I'm certainly not trying to hold back improvements. :) We had similar discussions in another thread later (see here) where I suggested to retire the spirv_headers create and use the spirv crate instead to have a clean slate for using semver. This might be the time to really push towards that.

[Jasper-Bekkers]

@antiagainst Agreed, filed #197 for further discussion around how to proceed :-)

[ErichDonGubler]

Given that #197 is closed now, does that this mean issue is resolved?
