Package: effect
Module: Effect

Effect.findFirstFilter

Returns the first value that passes an effectful FilterEffect.

When to use

Use when you need to find the first element that satisfies an effectful filter returning a Result, which also transforms the matching element.

Details

The filter receives the element and index. Evaluation short-circuits on the first Result.succeed and returns the transformed value in Option.some.

See

• findFirst for the simpler effectful predicate-based variant

Signature

declare const findFirstFilter: { <A, B, X, E, R>(filter: (input: NoInfer<A>, i: number) => Effect<Result.Result<B, X>, E, R>): (elements: Iterable<A>) => Effect<Option<B>, E, R>; <A, B, X, E, R>(elements: Iterable<A>, filter: (input: NoInfer<A>, i: number) => Effect<Result.Result<B, X>, E, R>): Effect<Option<B>, E, R>; }
