Assign to this object the value of the specified `rhs` object, propagate to this object the allocator of `rhs` if the `ALLOCATOR` type has trait `propagate_on_container_move_assignment`, and return a reference providing modifiable access to this object. The contents of `rhs` are moved (in constant time) to this vector if `get_allocator() == rhs.get_allocator()` (after accounting for the aforementioned trait); otherwise, all elements in this vector are either destroyed or move‐assigned to and each additional element in `rhs` is move‐inserted into this vector. `rhs` is left in a valid but unspecified state, and if an exception is thrown, `*this` is left in a valid but unspecified state. This method requires that the (template parameter) type `VALUE_TYPE` be `move‐assignable` and `move‐insertable` into this vector (see {Requirements on `VALUE_TYPE`}). Note that the `vector` template arguments must be explicitly spelled out to work around an MSVC 2022 bug, see DRQS 171087946.
