Assignment operators

== Synopses

Declared in `<bslstl_unorderedset.h>`

Assign to this object the value, hash function, and equality comparator 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 set if `get_allocator() == rhs.get_allocator()` (after accounting for the aforementioned trait); otherwise, all elements in this set are either destroyed or move‐assigned to and each additional element in `rhs` is move‐inserted into this set. `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 `KEY` be both `move‐assignable` and `move‐insertable` into this set (see {Requirements on `KEY`}).

Assign to this object the value resulting from first clearing this unordered set and then inserting each `value_type` object in the specified `values` initializer list, ignoring those keys having a value equivalent to that which appears earlier in the list; return a reference providing modifiable access to this object. This method requires that the (template parameter) type `KEY` type be `copy‐insertable` into this set (see {Requirements on `KEY`}).

Assign to this object the value, hash function, and equality comparator of the specified `rhs` object, propagate to this object the allocator of `rhs` if the `ALLOCATOR` type has trait `propagate_on_container_copy_assignment`, and return a reference providing modifiable access to this object. If an exception is thrown, `*this` is left in a valid but unspecified state. This method requires that the (template parameter) type `KEY` be `copy‐assignable` and 'copy‐insertable" into this set (see {Requirements on `KEY`}).
