Module clone_cell::cell

Shareable mutable containers.

When to use Cell

Cell::get only requires T to be PureClone. This is useful when working with with shared structs whose fields are of types Rc<T>, Weak<T>, Option<T: PureClone>, etc.

Note that just because there can be any number of readers and writers to a Cell does not mean it is always a good pattern. In most cases, it may not make sense to have more than one writer at a time. But the user can easily build zero-cost abstractions on top of a Cell to enforce this. For example, this may be useful when implementing the observer pattern.
