# NLOHMANN_JSON_NAMESPACE

    #define NLOHMANN_JSON_NAMESPACE

This macro evaluates to the full name of the `nlohmann` namespace, including the name of a versioned and ABI-tagged inline namespace. Use this macro to unambiguously refer to the `nlohmann` namespace.

## Default definition

The default value consists of a prefix, a version string, and optional ABI tags depending on whether ABI-affecting macros are defined (e.g., `JSON_DIAGNOSTICS`, and `JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON`).

When the macro is not defined, the library will define it to its default value.
