Struct RootedCell

#[repr(C)]
pub struct RootedCell<T> { /* private fields */ }

Analagous to std::cell::Cell. In particular like std::cell::Cell, it doesn’t perform any atomic operations internally, making it relatively inexpensive.

Unlike std::cell::Cell, this type is Send and Sync if T is Send. This is safe because the owner is required to prove access to the associated Root, which is ![Sync], to access.
