NLOHMANN_JSON_NAMESPACE

#define NLOHMANN_JSON_NAMESPACE /* value */

This macro evaluates to the full name of the nlohmann namespace.

Default definition

The default value consists of the root namespace (nlohmann) and an inline ABI namespace. See nlohmann Namespace for details.

When the macro is not defined, the library will define it to its default value. Overriding this value has no effect on the library.
