Function handleCurriedIsomorphicIterable

  • Takes a generator for iterables, then a generator for async iterables and last 2 iterables, using the proper generator automatically.

    Example

    const handle = handleCurriedIsomorphicIterable(
        iterable2 => iterable1 => function* () {
            yield* iterable2;
            yield* iterable1;
        }
    )(
        iterable2 => iterable1 => async function* () {
            yield* iterable2;
            yield* iterable1;
        }
    );

    handle(nonAsyncIterable)(nonAsyncIterable); // IterableIterator
    handle(asyncIterable)(nonAsyncIterable); // AsyncIterableIterator

    Type Parameters

    • Iterable2Item = unknown

    • Iterable1Item = unknown

    • Output = unknown

    Parameters

    • iterator: Unary<Iterable<Iterable2Item>, Unary<Iterable<Iterable1Item>, Function<ReadOnlyArray<never>, Generator<Output, void, void>>>>

      Function to be used with non async iterables.

    Returns ((asyncIterator) => (<Iterable2>(iterable2) => (<Iterable1>(iterable1) => Iterable2 extends {
            [asyncIterator]() => AsyncIterator<Iterable2Item, any, undefined>;
        }
        ? {
            [asyncIterator]() => AsyncIterableIterator<Output>;
            next(...args) => Promise<IteratorResult<Output, any>>;
            return?(value?) => Promise<IteratorResult<Output, any>>;
            throw?(e?) => Promise<IteratorResult<Output, any>>;
        }
        : Iterable1 extends {
                [asyncIterator]() => AsyncIterator<Iterable1Item, any, undefined>;
            }
            ? {

                return?(value?) => IteratorResult<Output, any>;
                throw?(e?) => IteratorResult<Output, any>;
            })))

    Curried function with iterator in context.
