Fields

Scala validation library written in Tagless Final.

ScaladexMaven CentralCI

  • Final Tagless. Choose any Effect, Validated, or Error types.
  • Informative. Error paths help understanding where the error occurred.
  • Expressive. Rich, extendable validation syntax.
  • Lightweight. The core module has no-dependencies.
  • Dauntless. Have no fear of complex validations with Rule type.
  • Short-circuit. Avoid running undesired validation side-effects.
