<pre />

Confirms worker identity, component multiplicity, and supported registration surfaces.

## Fields

### `identity: Option<WorkerIdentity>`

Required worker identity for lifecycle responses.

### `allows_multiple_components: bool`

#### `supported_surfaces`

<pre />

Returns an iterator which yields the valid enum values contained in `supported_surfaces`.

#### `push_supported_surfaces`
