Array of inputs to each batch call.

Calls the parser with a given input and optional configuration options.
If the input is a string, it creates a generation with the input as
text and calls parseResult. If the input is a BaseMessage, it
creates a generation with the input as a message and the content of the
input as text, and then calls parseResult.
The input to the parser, which can be a string or a BaseMessage.
Optional options: BaseCallbackConfigOptional configuration options.
A promise of the parsed output.
Return a new Runnable that maps a list of inputs to a list of outputs, by calling invoke() with each input.
Abstract parseParse the output of an LLM call.
LLM output to parse.
Optional callbacks: CallbacksParsed output.
Abstract parseParses the result of an LLM call. This method is meant to be implemented by subclasses to define how the output from the LLM should be parsed.
The generations from an LLM call.
Optional callbacks: CallbacksOptional callbacks.
A promise of the parsed output.
Parses the result of an LLM call with a given prompt. By default, it
simply calls parseResult.
The generations from an LLM call.
The prompt used in the LLM call.
Optional callbacks: CallbacksOptional callbacks.
A promise of the parsed output.
Optional callbacks: CallbacksCreate a new runnable sequence that runs each individual runnable in series, piping the output of one runnable into another runnable or runnable-like.
A runnable, function, or object whose values are functions or runnables.
A new runnable sequence.
Stream output in chunks.
Optional options: Partial<BaseCallbackConfig>A readable stream that is also an iterable.
Stream all output from a runnable, as reported to the callback system. This includes all inner runs of LLMs, Retrievers, Tools, etc. Output is streamed as Log objects, which include a list of jsonpatch ops that describe how the state of the run has changed in each step, and the final state of the run. The jsonpatch ops can be applied in order to construct state.

New configuration parameters to attach to the new runnable.
A new RunnableBinding with a config matching what's passed.
Create a new runnable from the current one that will try invoking other passed fallback runnables if the initial invocation fails.
Other runnables to call if the runnable errors.

A base class for output parsers that can handle streaming input. It extends the
BaseTransformOutputParserclass and provides a method for converting parsed outputs into a diff format.
