  • Returns an async-iterable sequence that invokes the specified factory function whenever a call to [Symbol.asyncIterator] has been made.

    Type Parameters

    • TSource

    Parameters

    • factory: ((signal?) => AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>)

      Async-iterable factory function to invoke for each call to [Symbol.asyncIterator].

        • (signal?): AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>

        • Parameters

          • Optional signal: AbortSignal

          Returns AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>
