BloombergLP::bslstl::HashTable<UnorderedMapKeyConfiguration<basic_string<char> const, pair<basic_string<char> const, Json>>, TransparentHash, TransparentEqualTo, allocator<pair<basic_string<char> const, Json>>>::operator=

Assign to this object the value, hasher, comparator, and maxLoadFactor 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. If this hash-table and rhs use the same allocator (after considering the aforementioned trait), all of the contents of rhs are moved to this hash-table in constant time; otherwise, all elements in this hash table are either destroyed or move-assigned to and each additional element in rhs is move-inserted into this hash-table. rhs is left in a valid but unspecified state. This method requires that the ValueType defined by the (template parameter) type KEY_CONFIG be both move-assignable and move-insertable into this hash-table (see {Requirements on KEY_CONFIG}).
