Import

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

Access RefCause.hasFails through the imported RefCause 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 hasFails: <E, Err, R>(ref: RefCause<E, Err, R>) => RefSubject.Computed<boolean, Err, R>;

Why

Makes has fails a live projection of the cause; consumers can sample it now or observe it without copying the source state.

Ownership and lifetime

The has fails view retains no independent state. An Effect read samples the source once; Fx observation follows later pushes and its observing Scope owns subscription cleanup.

Other public imports

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