A collection of RxJS operators and utilities to enhance reactive programming capabilities.

import { Observable } from 'rxjs';
/**
 * Switches to a fallback Observable if the source doesn't emit within the specified timeout.
 * Unlike the standard timeout operator, this doesn't error but switches to the fallback.
 *
 * @param timeout - Timeout duration in milliseconds
 * @param fallback - Observable to switch to on timeout
 * @returns A function that returns an Observable that emits from source or fallback
 *
 * @example
 * ```typescript
 * // Switch to fallback after 5 seconds
 * source$.pipe(
 *   timeoutWithFallback(5000, of('timeout'))
 * )
 *
 * // Switch to alternative data source on timeout
 * source$.pipe(
 *   timeoutWithFallback(3000, alternativeSource$)
 * )
 * ```
