Issue

The PersistentDescriptorSet is designed to be immutable (the update method is private), which works great if I don't want to update my descriptor set. However, I do, and using UnsafeDescriptorSet by itself doesn't work because, unlike with PersistentDescriptorSet, I can't bind UnsafeDescriptorSet using the AutoCommandBufferBuilder::bind_descriptor_sets method, because neither UnsafeDescriptorSet nor Vec<UnsafeDescriptorSet> implements DescriptorSetsCollection trait.

Are there plans to add a MutableDescriptorSet struct that implements DescriptorSetsCollection, similar to PersistentDescriptorSet, but with a public update method? If not, can there be plans to do so? I would be happy to implement it and make a PR, if that's helpful. Thanks!

This was added by #2404 and will be part of the next Vulkano release, 0.35.
