Typedef Documentation

Container

using nlohmann::Container = std::vector<std::pair<const Key, T>, Allocator>

json

using nlohmann::json = basic_json<>

default JSON class

This type is the default specialization of the basic_json class which uses the standard template types.

Since

version 1.0.0

mapped_type

using nlohmann::mapped_type = T

ordered_json

using nlohmann::ordered_json = basic_json<nlohmann::ordered_map>

ordered JSON class

This type preserves the insertion order of object keys.

Since

version 3.9.0
