Functions ¶

func ContextWithTraceContext ¶

func ContextWithTraceContext(ctx context.Context, ev json.RawMessage) (context.Context, error)

ContextWithTraceContext uses the incoming event and/or context object payloads to determine the current TraceContext and then adds that TraceContext to the context object

Types ¶

type Config ¶

type Config struct {
	DDTraceEnabled  bool
	MergeXrayTraces bool
}

Config gives options for how the Listener should work

type Listener ¶

type Listener struct {
	// contains filtered or unexported fields
}

Listener creates a function execution span and injects it into the context

func MakeListener ¶

func MakeListener(config Config) Listener

MakeListener initializes a new trace lambda Listener

func (*Listener) HandlerFinished ¶

func (l *Listener) HandlerFinished(ctx context.Context)

HandlerFinished finishes the function execution span (if it was started) and stops the tracer

func (*Listener) HandlerStarted ¶

func (l *Listener) HandlerStarted(ctx context.Context, msg json.RawMessage) context.Context

HandlerStarted creates the function execution span representing the Lambda function execution and adds that span to the context so that the user can create child spans (if Datadog tracing is enabled)

type TraceContext ¶

type TraceContext map[string]string

TraceContext is map of headers containing a Datadog trace context

func GetTraceHeaders ¶

func GetTraceHeaders(ctx context.Context, useCurrentSegmentAsParent bool) TraceContext

GetTraceHeaders retrieves the current trace headers that should be added to outbound requests
