isAsyncData

Import

import { isAsyncData } from "@typed/async-data";

Signatures

export declare const isAsyncData: <A, E>(u: unknown) => u is AsyncData<A, E>;

Why

Boundary validation rejects malformed progress, failure causes, and cyclic optimistic histories before application logic depends on them.

Ownership and lifetime

Validation is iterative, acquires no resources, and retains no visited objects after returning.

Examples

import { isAsyncData } from "@typed/async-data"
isAsyncData({ _tag: "Loading", progress: { loaded: 1 } })
