Cause.CauseReducer

Describes methods for reducing a Cause<E> into a value of type Z with access to contextual information.

Details

This interface is meant for advanced transformations of Cause. By implementing each method, you can define how different parts of the Cause structure (like Fail, Die, or Interrupt) should be transformed into a final type Z. The context parameter carries additional data needed during this reduction.

export interface CauseReducer<in C, in E, in out Z> {
  emptyCase(context: C): Z
  failCase(context: C, error: E): Z
  dieCase(context: C, defect: unknown): Z
  interruptCase(context: C, fiberId: FiberId.FiberId): Z
  sequentialCase(context: C, left: Z, right: Z): Z
  parallelCase(context: C, left: Z, right: Z): Z
}
