Struct LambdaXrayPropagator

pub struct LambdaXrayPropagator { /* private fields */ }

A custom propagator that wraps the XrayPropagator with Lambda-specific enhancements.

This propagator extends the standard X-Ray propagator to automatically extract trace context from the Lambda _X_AMZN_TRACE_ID environment variable when no valid context is found in the provided carrier.

Example

use lambda_otel_lite::{init_telemetry, TelemetryConfig};
use lambda_otel_lite::propagation::LambdaXrayPropagator;
use opentelemetry::global;
use lambda_runtime::Error;

// Add the LambdaXrayPropagator
let config = TelemetryConfig::builder()
    .with_named_propagator("tracecontext")
    .with_named_propagator("xray-lambda")
    .build();

let _ = init_telemetry(config).await?;

Implementations

impl LambdaXrayPropagator

pub fn new() -> Self

Create a new instance of the LambdaXrayPropagator.

Trait Implementations

impl Debug for LambdaXrayPropagator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LambdaXrayPropagator

fn default() -> LambdaXrayPropagator

Returns the “default value” for a type.

impl TextMapPropagator for LambdaXrayPropagator

fn fields(&self) -> FieldIter<'_>

Returns iter of fields used by TextMapPropagator

fn extract_with_context( &self, cx: &Context, extractor: &dyn Extractor, ) -> Context

Retrieves encoded data using the provided Extractor. If no data for this format was retrieved OR if the retrieved data is invalid, then the given Context is returned.

fn extract(&self, extractor: &dyn Extractor) -> Context

Retrieves encoded data using the provided Extractor. If no data for this format was retrieved OR if the retrieved data is invalid, then the current Context is returned.

fn inject_context(&self, cx: &Context, injector: &mut dyn Injector)

Properly encodes the values of the Context and injects them into the Injector.

fn inject(&self, injector: &mut dyn Injector)

Properly encodes the values of the current Context and injects them into the Injector.
