JSON_HAS_RANGES

#define JSON_HAS_RANGES /* value */

This macro indicates whether the standard library has any support for ranges. Implies support for concepts. Possible values are 1 when supported or 0 when unsupported.

Default definition

The default value is detected based on the preprocessor macro #!cpp __cpp_lib_ranges.

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

  • Added in version 3.11.0.
