    Provides a simple mechanism to insert derived type class instances in the implicit resolution mechanism.

    Provides a simple mechanism to insert derived type class instances in the implicit resolution mechanism.

    By default, when imported, such instances have the highest possible priority, which is typically problematic with shapeless instance derivation: bespoke instances for Option or Either, for example, find themselves shadowed by the generically derived ones.

    If such instances are of type kantan.codecs.export.DerivedDecoder / kantan.codecs.export.DerivedEncoder rather than Decoder / Encoder, however, they'll find themselves with a lower precedence and only be used if no other, more specific instance is found.

    Defines codecs for encoding to and decoding from strings.

    Defines codecs for encoding to and decoding from strings.

    These codecs are not necessary meant to use directly, but more as part of larger ones. kantan.csv, for example, works with CSV files but delegates the act of encoding to or decoding from a CSV cell to string codecs.

    Default instances can be found in kantan.codecs.strings.codecs.

Type Members

  1. abstract class Error extends Exception with Product with Serializable

    Base class for errors

    Base class for errors

    This is specifically meant for errors represented as ADTs. The fact that it extends Exception is an unfortunate side effect of the Scala stdlib's reliance on exceptions, as seen with scala.concurrent.Future and scala.util.Try, for example.

  2. abstract class ErrorCompanion[T <: Error] extends Serializable

    Provides useful instance creation methods for errors that might be created as a result of Java exceptions.

  3. trait IsError[E] extends Serializable

    Type class for types that can be used as errors.

    Type class for types that can be used as errors.

    This is mostly meant to work in conjunction with Error, and lets code that deals with errors turn them into values of the right error type.
