streamFromInputStream method

@override Stream<PromptValue> streamFromInputStream(Stream<InputValues> inputStream, { BaseLangChainOptions? options, })

Streams the output of invoking the Runnable on the given inputStream.

• inputStream - the input stream to invoke the Runnable on.
• options - the options to use when invoking the Runnable.

Implementation

@override
Stream<PromptValue> streamFromInputStream(
  final Stream<InputValues> inputStream, {
  final BaseLangChainOptions? options,
}) async* {
  final List<InputValues> input = await inputStream.toList();
  final InputValues reduced =
      input.isEmpty ? const {} : reduce<InputValues>(input);
  yield* stream(reduced, options: options);
}
