StateSetter<T> class final

A ref-like state setter that supports direct and functional updates.

Calling the setter with a value replaces the state. Calling update lets a renderer apply an updater against the current state.

See https://react.dev/reference/react/useState#updating-state-based-on-the-previous-state.
