def lens[F[_], A, B](ref: SignallingRef[F, A])(get: A => B, set: A => B => A)(implicit F: Functor[F]): SignallingRef[F, B]

Creates an instance focused on a component of another SignallingRef's value.

Creates an instance focused on a component of another SignallingRef's value. Delegates every get and modification to underlying SignallingRef, so both instances are always in sync.
