# JSON_HAS_RANGES
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#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.
