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_lib_ranges
