bsl::unordered_map<basic_string<char>, Json, TransparentHash, TransparentEqualTo>::max_load_factor

Set the maximum load factor of this unordered map to the specified newMaxLoadFactor. If newMaxLoadFactor < loadFactor(), this operator will cause an immediate rehash (in violation of the C++11 standard); otherwise, it has a constant‐time cost. The behavior is undefined unless 0 < newMaxLoadFactor.
