/**
  `catchErrorSource` is a custom RxJS [operator](https://rxjs.dev/guide/operators) that converts an RxJS [Observable](https://rxjs.dev/guide/observable)
  of any values into a source of errors, using RxJS' [catchError](https://rxjs.dev/api/operators/catchError) operator.
  It takes one argument, {@link TypePrefix}, and prefixes it to create an object of type {@link Action}<any, ${{@link TypePrefix}}.error$>.

  #### Example: Catching errors from a source

  ```typescript
  import { timer, map } from 'rxjs';

  const timer$ = timer(1000).pipe(
    map(n => ({ type: 'timer$', payload: n.fakeNumberMethod() })),
    catchErrorSource('timer'),
  );

  timer$.subscribe(console.log);
  // { type: 'timer.error$', payload: 'Error: n.fakeNumberMethod is not a function' }
  ```
 */
export declare function catchErrorSource<Payload, TypePrefix extends string>(typePrefix: TypePrefix): (source$: Observable<Payload>) => Observable<Payload | Action<any, `${TypePrefix}.error$`>>;
