Follow one execution
Return a Fiber immediately; joining it later yields the full collected array.
collectAllForkTick 0. Scope: start; Effect: Fiber.

Follow each lane from left to right. Events stacked vertically share a tick; the green cursor marks the current time across every lane.
- A value
The text inside the pill is the emitted value. - Work starts
The raised chevron starts an inner run (^in the source). - The run returns
The vertical bar ends this lane’s run. - A cause is delivered
The exclamation mark belongs to this lane. - Work is interrupted
The cross marks cancellation of this run. - Current time
The line and diamond move together across all lanes. - Happening now
A highlighted event is at the current tick. - Still ahead
Muted, dashed values have not happened yet. - Time continues
The lane’s arrow is not a return marker. An empty stretch can be quiet work that is still running.
Illustrated ticks start at 0. At 1×, one illustrated tick takes one second; captions specify real durations when timing matters. A cause or interruption belongs to its lane, and other work may continue. Scroll horizontally to inspect the rest of a long timeline.
Running the returned Effect starts a child fiber immediately. The parent fiber’s scope supervises it, so parent termination interrupts collection. The child retains every value until completion and exposes source failure as its E channel.
Import
import { collectAllFork } from "@typed/fx/Fx";Signatures
export declare const collectAllFork: <A, E = never, R = never>(fx: Fx<A, E, R>) => Effect.Effect<Fiber.Fiber<ReadonlyArray<A>, E>, never, R>;Why
Collection can proceed concurrently while the caller retains a typed Fiber for
awaiting, polling, or interruption.
Ownership and lifetime
Running the returned Effect starts a child fiber immediately. The parent fiber’s
scope supervises it, so parent termination interrupts collection. The child retains
every value until completion and exposes source failure as its E channel.
Examples
import { Effect, Fiber } from "effect"
import { collectAllFork, fromIterable } from "@typed/fx/Fx"
const program = Effect.gen(function* () {
const fiber = yield* collectAllFork(fromIterable([1, 2, 3]))
return yield* Fiber.join(fiber)
