Equality function that doesn't check sType or pNext

[mbechard]

Hey, similar to StructureChain::assign, it would useful if there was a function that could compare the equality of two Structures, without looking at sType or pNext. That way the 'real' values of the struct can be compared more easily.
Thanks

Well, yes, that could be a set of compare functions for structures with a pNext member, ignoring that member.
sType should be trivially identical anyways, as you should only be able to compare identical structure types.

Would extend the vulkan_structs.hpp file a bit more, though.

Do you have a 'real' use case where that functionality would be useful and simplify code?

Thanks for the consideration. The one usage case I've run into is a vk::StructureChain<vk::SubpassDependency2, vk::MemoryBarrier2> that I've held onto as a way to check if a need to create a new vk::RenderPass.
If it'll make the .hpp file needlessly large, may it can only be implemented in vk::StructureChain. I'm not too familiar with new C++reflection features, but if it's also only available when that is enabled, that's fine too.
Thanks

Thank you!
