Expand description

A storage that can manage multiple memory handles.

allocate no longer invalidates existing handles. You can allocate multiple handles that are all valid at the same time. This does not change the requirements of resolve or resolve_mut; only one pointer returned from resolve_mut is valid at a time.

In addition, grow and shrink are implemented at least at least as well as creating a new handle and copying over the old contents. (This is provided by default impl.)

Required Methods

source

unsafe fn resolve_many_mut<const N: usize>(
&mut self,
handles: [(Self::Handle, Layout ); N]
) -> [&mut Memory ; N]

Resolve memory handles in this storage to mutable references.

Safety

The handles 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.
The same handle must not be resolved twice in a single call.
