Struct RagRunnable 

pub struct RagRunnable { /* private fields */ }

Adapter that wraps a RAGPipeline as a Runnable<String, String>.

This enables RAG pipelines to participate in LCEL pipelines:

let rag_runnable = RagRunnable::new(Arc::new(pipeline));
let pipeline = rag_runnable.pipe(parser);

Implementations

impl RagRunnable

pub fn new(pipeline: Arc<RAGPipeline>) -> Self

Create a new adapter wrapping the given RAG pipeline.

Trait Implementations

impl Runnable<String, String> for RagRunnable

type Error = LcelError

Error type.

fn invoke<'life0, 'async_trait>( &'life0 self, input: String, _config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<String, LcelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Transforms single input to output.

fn batch<'life0, 'async_trait>( &'life0 self, inputs: Vec<Input>, config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<Vec<Output>, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Batch processing - transforms multiple inputs to outputs.

fn batch_as_completed<'life0, 'async_trait>( &'life0 self, inputs: Vec<Input>, config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<Vec<(usize, Output)>, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Batch processing that returns results in completion order.

fn stream<'life0, 'async_trait>( &'life0 self, input: Input, config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Output, Self::Error>> + Send>>, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Streaming output - for real-time responses (LLM, etc).

fn transform<'life0, 'async_trait>( &'life0 self, input: Pin<Box<dyn Stream<Item = Result<Input, Self::Error>> + Send>>, config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Output, Self::Error>> + Send + 'life0>>, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Stream-to-stream transformation - the core of LCEL streaming.
