Allow `ListSerializer` to parse partial good results and ignore bad ones

What is your use-case and why do you need this feature? I’m receiving a list of items from the server. Some of the items might miss some required fields or be otherwise malformed. In this case, I would like to ignore the items that failed to parse but still parse the ones that I can. Unfortunately, it looks like ListSerializer is failing as soon as it encounters a single list item which it fails to parse.

Describe the solution you’d like Some sort of ignoreFailedListItems or allowPartialListResults configuration.

*This probably applies to all collections.

A serializer for a type with generic parameter will need a constructor that takes a serializer for that generic parameter. In this case you want to use @SerializeWith(KindListSerializer::class), you don’t need to create a subclass for the parameter type (that will actually not work as you found).

It looks like the error is imprecise. If your CustomDataSerializer is a serializer for List, it should be applied to the List, not to its generic type arg: val data: @Serializable(CustomDataSerializer::class) List<Data>
