arrow-typed-errors

To model typed errors with Arrow's Raise context, define domain-specific failures within context-parameter computations and use wrappers like Either, Option, or Ior to propagate them across multi-step workflows.

Domain failures are expected logical errors modeled by typed wrappers like Either and Ior, whereas exceptional faults are unexpected runtime crashes. Distinguishing them before selecting an API ensures correct error propagation strategy.

To accumulate validation errors in Kotlin, use Arrow's Ior wrapper within the Raise DSL to collect independent defects across input validation steps, providing richer error reporting rather than stopping at the first failure.

Yes, you can translate error types across boundaries in nested Kotlin computations by leveraging Arrow's context-parameter API to map and propagate different typed errors through dependent multi-step logic layers.

Use Either to model success or specific failure, Option for presence or absence, and Ior when you need to accumulate independent defects for richer validation while continuing computation across multi-step workflows.

Yes, Arrow's context-parameter API simplifies verbose Either handling by allowing typed errors to be raised contextually, reducing boilerplate when propagating failures across nested computations and boundary translations.
