# Objective While working on #8299, I noticed that we're using a `capacity` field, even though `wgpu::Buffer` exposes a `size` accessor that does the same thing. ## Solution Remove it from all buffer wrappers. Use `wgpu::Buffer::size` instead. Default to 0 if no buffer has been allocated yet.

Objective
Fixes #8284.
valuesis being pushed to separately from the actual scratch buffer inDynamicUniformBuffer::pushandDynamicStorageBuffer::push. In both types,valuesis really only used to track the number of elements being added to the buffer, yet is causing extra allocations, size increments and excess copies.Solution
Remove it and its remaining uses. Replace it with accesses to
scratchinstead.I removed the
lenaccessor, as it may be non-trivial to compute just fromscratch. If this is still desirable to have, we can keep alenmember field to track it instead of relying onscratch.
