Expand description

A storage that serves as a uniqueness barrier.

Notably, this means that this storage can go &Storage -> &mut Memory, and thus it is possible to mutate the stored memory behind a shared storage reference, and to mutably resolve multiple handles separately without invalidating previously resolved handles.

Required Methods

Resolve a memory handle in this storage to a mutable reference.

Safety
  • The handle must have been created by this storage, and must not have been invalidated.
  • The layout must be the same as used to allocate the handle.
