Follow one execution
Run the Effect once per subscription and flatten the Fx it returns.

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.
Acquisition and inner failures are forwarded and both environments remain in the returned type. unwrap does not create a Scope or hide one: interruption stops whichever phase is active, and any resourceful Effect or inner Fx must expose and receive its own Scope requirement.
Import
import { unwrap } from "@typed/fx/Fx";Signatures
export declare const unwrap: <A = never, E = never, R = never, E2 = never, R2 = never>(effect: Effect.Effect<Fx<A, E, R>, E2, R2>) => Fx<A, E | E2, R | R2>;Why
unwrap defers choosing or acquiring a producer until observation, while
keeping the Effect and the selected Fx in one typed push pipeline.
Execution and cardinality
Each observation runs effect once. On success, the produced Fx is observed
and all of its values are forwarded in order. The acquisition Effect itself
emits no value, and the inner is never started if acquisition fails.
Ownership and lifetime
Acquisition and inner failures are forwarded and both environments remain in
the returned type. unwrap does not create a Scope or hide one: interruption
stops whichever phase is active, and any resourceful Effect or inner Fx must
expose and receive its own Scope requirement.
Examples
import { Fx } from "@typed/fx"
import { Effect } from "effect"
const selected = Fx.unwrap(
Effect.succeed(Fx.fromIterable(["ready", "running"]))
