Import

import { RefArray } from "@typed/fx";

Access RefArray.takeWhile through the imported RefArray export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare const takeWhile: {
    <A>(predicate: (a: A) => boolean): <E, R>(ref: RefArray<A, E, R>) => Effect.Effect<ReadonlyArray<A>, E, R>;
    <A, E, R>(ref: RefArray<A, E, R>, predicate: (a: unknown) => boolean): Effect.Effect<ReadonlyArray<A>, E, R>;
};

Why

Applies take while to the committed array value and publishes only the result, preserving its element order and equality rules.

Ownership and lifetime

Running take while performs one serialized array transition and resolves with its committed value. It acquires no resource; failures and services remain those of the source ref.

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
