This is perfectly fine because we already have `cap == 0` as our sentinel for no allocation. We don't even need to handle it specially in almost any code because we usually need to check if `cap > len` or `len > 0` anyway. The recommended -Rust value to put here is `mem::size_of::()`. `NonNull` provides a convenience +Rust value to put here is `mem::align_of::()`. `NonNull` provides a convenience for this: `NonNull::dangling()`. There are quite a few places where we'll want to use `dangling` because there's no real allocation to talk about but `null` would make the compiler do bad things.
