 abstract T visitUser(User user)
```
    A /concepts/users represents an individual in your system who can receive notifications through Knock. Users are the most common recipients of notifications and are always referenced by your internal identifier.
  - visitObject
```
 abstract T visitObject(Object object_)
```
    A custom /concepts/objects entity which belongs to a collection.
  - unknown
```
 T unknown(JsonValue json)
```
    Maps an unknown variant of Recipient to a value of type T.
    An instance of Recipient can contain an unknown variant if it was deserialized from data that doesn't match any known variant. For example, if the SDK is on an older version than the API, then the API may respond with new variants that the SDK is unaware of.
