Effect.catchCauseFilter

Recovers from specific failures based on a Filter.

When to use

Use when you need to recover an Effect only from causes selected by a Filter, while giving the recovery both the selected value and the original Cause.

Details

The filter is applied to the full Cause. When it succeeds, the handler receives the selected value and the original cause. When it fails, the effect re-fails with the residual cause returned by the filter.

See

• catchCauseIf for predicate-based cause selection
• catchFilter for filtering typed error values instead of full causes
• catchCause for recovering from every cause without filtering

Signature

declare const catchCauseFilter: { <E, B, E2, R2, EB, X extends Cause.Cause<any>>(filter: Filter.Filter<Cause.Cause<E>, EB, X>, f: (failure: EB, cause: Cause.Cause<E>) => Effect<B, E2, R2>): <A, R>(self: Effect<A, E, R>) => Effect<A | B, Cause.Cause.Error<X> | E2, R | R2>; <A, E, R, B, E2, R2, EB, X extends Cause.Cause<any>>(self: Effect<A, E, R>, filter: Filter.Filter<Cause.Cause<E>, EB, X>, f: (failure: EB, cause: Cause.Cause<E>) => Effect<B, E2, R2>): Effect<A | B, Cause.Cause.Error<X> | E2, R | R2>; }
