Struct forth3::dictionary::SharedDict

pub(crate) struct SharedDict<T: 'static>(NonNull<Dictionary<T>>);

A handle to a shared, atomically reference counted dictionary allocation.

The contents of this dictionary are frozen and can no longer be mutated. However, a SharedDict can be inexpensively cloned by incrementing its reference count.

When a VM is forked into a child VM, its current OwnedDict is transformed into a SharedDict, which both its new OwnedDict and the child VM’s OwnedDict will reference as their parents.
