Struct SqsEventExtractor 

pub struct SqsEventExtractor;

Extractor for SQS message events.

SQS events carry trace context in the AWSTraceHeader system attribute using X-Ray format. This extractor:

1. Does NOT set a parent context (returns current context)
2. Creates span links for each message’s trace context

This follows OpenTelemetry semantic conventions for messaging systems, where the async nature of message queues means span links are more appropriate than parent-child relationships.

Example

use opentelemetry_lambda_tower::{OtelTracingLayer, SqsEventExtractor};

let layer = OtelTracingLayer::new(SqsEventExtractor::new());
