Struct Each 

pub struct Each<R, I, O> { /* private fields */ }

Wraps a Runnable<I, O> to act on a Vec<I> element-wise.

Concurrency is bounded by RunnableConfig::max_concurrency. Output order matches input order.

Implementations

impl<R, I, O> Each<R, I, O>

where R: Runnable<I, O>, I: Send + 'static, O: Send + 'static,

pub fn new(inner: R) -> Self

Wrap a runnable so it operates element-wise on a Vec<I>.

Trait Implementations

impl<R, I, O> Runnable<Vec<I>, Vec<O>> for Each<R, I, O>

where R: Runnable<I, O>, I: Send + 'static, O: Send + 'static,

fn invoke<'life0, 'async_trait>( &'life0 self, inputs: Vec<I>, config: RunnableConfig, ) -> Pin<Box<dyn Future<Output = Result<Vec<O>>> + Send + 'async_trait>>

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

One-shot invocation. The hot path.

fn name(&self) -> &str

Friendly name for telemetry / introspection.

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

where I: 'static, O: 'static, Self: Sized + Sync + 'async_trait, 'life0: 'async_trait,

Run multiple inputs in parallel. Defaults to buffer_unordered honouring config.max_concurrency.

fn stream<'life0, 'async_trait>( &'life0 self, input: I, config: RunnableConfig, ) -> Pin<Box<dyn Future<Output = Result<RunnableStream<O>>> + Send + 'async_trait>>

where Self: Sized + Sync + 'async_trait, 'life0: 'async_trait,

Stream the final output (chunks of O). Default emits one item via invoke — non-streaming runnables are correct without override.

fn stream_events<'life0, 'async_trait>( &'life0 self, input: I, config: RunnableConfig, ) -> Pin<Box<dyn Future<Output = Result<EventStream>> + Send + 'async_trait>>

where I: Serialize, O: Serialize, Self: Sized + Sync + 'async_trait, 'life0: 'async_trait,

Stream structured events. Default emits OnStart + OnEnd around an invoke call. Graph engines override to surface per-node events.

fn input_schema(&self) -> Option<Value>

JSON Schema for the input type, if known.

fn output_schema(&self) -> Option<Value>

JSON Schema for the output type, if known.
