# std::hash<basic_json\>
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
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.
