This means * components that use this hook will rerender when the resolved atom instance's * state changes. * * Also accepts an atom instance and subscribes to updates in the passed * instance. * * If the atom doesn't take params or an instance is passed, pass an empty array * for the 2nd param when you need to supply the 3rd `config` param. * * Returns a [state, setState] tuple. The `setState` function is * "export-infused", meaning it has all of the atom instance's `exports` * attached directly to the function. These can be destructured for convenience: * * ```ts * const [state, { decrement, increment }] = useAtomState(myCounterAtom) * ``` * * The 3rd param is a `config` object which can be given `operation` and * `suspend` fields: * * ```ts * const [state, setState] = useAtomState(myAtom, [], { * operation: 'myUsageDescription', // helps with debugging * suspend: false, // disable React suspense if the atom set a promise * }) * ``` */ export declare const useAtomState: { <A extends AnyAtomTemplate>(template: A, params: AtomParamsType<A>, config?: Omit<ZeduxHookConfig, 'subscribe'>): StateHookTuple<AtomStateType<A>, AtomExportsType<A>>; <A extends AnyAtomTemplate<{ Params: []; }>>(template: A): StateHookTuple<AtomStateType<A>, AtomExportsType<A>>; <A extends AnyAtomTemplate>(template: ParamlessTemplate<A>): StateHookTuple<AtomStateType<A>, AtomExportsType<A>>; <I extends AnyAtomInstance>(instance: I, params?: [], config?: Omit<ZeduxHookConfig, 'subscribe'>): StateHookTuple<AtomStateType<I>, AtomExportsType<I>>; };
