std::hashnlohmann::basic_json\
namespace std {
struct hash<nlohmann::basic_json>;
}
Return a hash value for a JSON object. The hash function tries to rely on std::hash where possible. Furthermore, the
type of the JSON value is taken into account to have different hash values for #!json null, #!cpp 0, #!cpp 0U, and
#!cpp false, etc.
Examples
??? example
The example shows how to calculate hash values for different JSON values.
```cpp
--8<-- "examples/std_hash.cpp"
```
Output:
```json
--8<-- "examples/std_hash.output"
```
Version history
- Added in version 1.0.0.
