DiscriminatorKind

Represents the strategy for specifying the discriminator used in a JSON schema for distinguishing between different subtypes of a sealed hierarchy.

Implementations of this trait define how the discriminator is represented in the serialized JSON, if any.

The possible discriminator kinds include:

• Field with adding a custom field named as specified in the name parameter that contains a value of the subtype discriminator, e.g. {"type": "Person", ...} for case class Person(...) extends SealedTrait
• Key, where the discriminator is represented as a JSON object key with wrapping of the encoded value in a JSON object, e.g. {"Person":{...}} for case class Person(...) extends SealedTrait.
• None, where no discriminator is used, meaning subtype differentiation is handled by sequential attempts to parse all possible subtypes, starting from the first subtype, until a successful parse is found, or an error is thrown if none of the subtypes can be parsed from the input.
