What problem does it solve?

Streamlines derivation of type-class instances for sealed traits and Scala 3 enums using Hearth's Enum.parse API, enabling exhaustive pattern matching and consistent error messages across Scala versions.

Core Features & Use Cases

  • Derive type-class instances for sealed hierarchies and Scala 3 enums via Enum.parse and per-case dispatch.
  • Distinguish singleton enum cases from case classes and handle recursive structures with supported tricks.
  • Support discriminator-style decoding in streaming codecs and wrapper inline modes for nested data.
  • Use in codebases that target Scala 2.13 or Scala 3, with forwards-compatibility and macro-based derivation.

Quick Start

Instantiate Enum.parse on your sealed trait or Scala 3 enum and combine per-case derivations with parMatchOn to cover all cases.
