Struct OtelTracingService

pub struct OtelTracingService<S, T: SpanAttributesExtractor> { /* private fields */ }

Tower service returned by OtelTracingLayer.

This service wraps the inner Lambda service to:

1. Create a span for each invocation
2. Extract and set span attributes
3. Propagate context from headers
4. Track response status
5. Signal completion for span export

The service is created automatically by the layer - you shouldn’t need to construct it directly.

Trait Implementations

impl<S: Clone, T: Clone + SpanAttributesExtractor> Clone for OtelTracingService<S, T>

fn clone(&self) -> OtelTracingService<S, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, F, T, R> Service<LambdaEvent<T>> for OtelTracingService<S, T>

where S: Service<LambdaEvent<T>, Response = R, Error = Error, Future = F> + Send, F: Future<Output = Result<R, Error>> + Send + 'static, T: SpanAttributesExtractor + DeserializeOwned + Serialize + Send + 'static, R: Serialize + Send + 'static,

type Response = R

Responses given by the service.

type Error = Box<dyn Error + Sync + Send>

Errors produced by the service.

type Future = CompletionFuture<Instrumented<<S as Service<LambdaEvent<T>>>::Future>>

The future response value.

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, event: LambdaEvent<T>) -> Self::Future

Process the request and return the response asynchronously.
