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}).
