trait ShapelessInstances extends AnyRef

Provides Codec instances for case classes and sum types.

The purpose of this package is to let concrete Codec implementations (such as kantan.csv or kantan.regex) focus on providing instances for HList and Coproduct. Once such instances exist, this package will take care of the transformation from and to case classes and sum types.

Additionally, instances derived that way will be inserted with a sane precedence in the implicit resolution mechanism. This means, for example, that they will not override bespoke Option or Either instances.

    Provides a Decoder instance for case classes.

    Provides a Decoder instance for case classes.

    Given a case class D, this expects n Decoder instance for the HList type corresponding to D. It will then rely on that to turn encoded values into an HList, then turn the resulting value into a D.

    Provides an Encoder instance for case classes.

    Given a case class D, this expects an Encoder instance for the HList type corresponding to D. It will then simply turn values of type D into values of the corresponding HList, then let the encoder take it from there.
