## Structs

### `App`

Object that represents the application operating in the protocol, e.g. "Sage", "instagram-clone", "bucket", or "double-up". Developers may create different apps within the protocol to build social applications or augment their application with social capabilities.

```rust theme={null}
public struct App has key
```

<Expandable title="Fields">
  ```rust theme={null}
    id: UID,
    name: String,
    rewards_enabled: bool
  ```
</Expandable>

### `AppRegistry`

Registry that maintains a reference to every `App` on the protocol and maintains name-uniqueness.

```rust theme={null}
public struct AppRegistry has key
```

<Expandable title="Fields">
  ```rust theme={null}
    id: UID,
    registry: Table<String, address>
  ```
</Expandable>

## Functions

Returns the address of the `App`'s id.

```rust theme={null}

    }
  ```
</Expandable>

### `get_name`

    ): String {
        app.name
    }
  ```
</Expandable>

### `has_record`

Returns `true` if the case-insensitive app name is already in use, and `false` otherwise.

```rust theme={null}
public fun has_record(app: &App): bool
```

<Expandable title="Implementation">
  ```rust theme={null}
    public fun has_record(
        app_registry: &AppRegistry,
        app_key: String
    ): bool {
        app_registry.registry.contains(app_key)
    }
  ```
</Expandable>
