Struct ApiGatewayV2Extractor 

pub struct ApiGatewayV2Extractor;

Extractor for API Gateway HTTP API (v2) events.

Extracts trace context from HTTP headers using the globally configured OpenTelemetry propagator. Falls back to the _X_AMZN_TRACE_ID environment variable if no valid trace context is found in headers.

Configure the propagator via opentelemetry::global::set_text_map_propagator().

Example

use opentelemetry_lambda_tower::{OtelTracingLayer, ApiGatewayV2Extractor};

let layer = OtelTracingLayer::new(ApiGatewayV2Extractor::new());
