# basic_json::boolean_t

```cpp
using boolean_t = BooleanType;
```

The type used to store JSON booleans.

[RFC 8259](https://tools.ietf.org/html/rfc8259) implicitly describes a boolean as a type which differentiates the two literals
`#!json true` and `#!json false`.

To store objects in C++, a type is defined by the template parameter  `BooleanType` which chooses the type to use.

## Notes

#### Default type

With the default values for `BooleanType` (`#!cpp bool`), the default value for `boolean_t` is `#!cpp bool`.

#### Storage

Boolean values are stored directly inside a `basic_json` type.
