bsl::unordered_multimap::operator=

Assign to this object the value, hash function, and key-equivalence 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) types KEY and VALUE both be copy-assignable and copy-insertable into this unordered multimap (see {Requirements on KEY and VALUE}).
