Destroy the current target (if any) of this object, then set the target to the specified `rhs` wrapper containing a reference to a callable object and return `*this`. The result is equivalent to having constructed `*this` from `rhs` and `this‐>get_allocator()`. Note that this assignment is a separate overload only because it is unconditionally `noexcept`.
