  abstract class ParcelableSerializer<T : Parcelable> : KSerializer<T>
  ```

*** ** * ** ***

A serializer for `https://developer.android.com/reference/android/os/Parcelable.html`. This serializer uses `https://developer.android.com/reference/kotlin/androidx/savedstate/SavedState`'s API directly to save/load a `https://developer.android.com/reference/android/os/Parcelable.html`. You must extend this serializer for each of your `https://developer.android.com/reference/android/os/Parcelable.html` subclasses.

Note that this serializer should be used with `https://developer.android.com/reference/kotlin/androidx/savedstate/serialization/SavedStateEncoder` or `https://developer.android.com/reference/kotlin/androidx/savedstate/serialization/SavedStateDecoder` only. Using it with other Encoders/Decoders may throw `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-illegal-argument-exception/index.html`.

```kotlin
import androidx.savedstate.serialization.serializers.ParcelableSerializer

@Serializable
data class MyModel(
    @Serializable(with = MyParcelableSerializer::class) val parcelable: MyParcelable
)
```
