Functions

func GetTracer

func GetTracer(service string) trace.Tracer

func Init

func Init(serviceName string) (func(), error)

func StartSpan

func StartSpan(baseCtx context.Context, service string, format string, args ...interface{}) (context.Context, trace.Span)

Types

type TraceCtx

	Ctx  context.Context
	Span trace.Span
}

TraceCtx is a struct which contains a span and the associated context This is used by the FDW for persisting [`span`,`context`] tuples across PostreSQL callbacks
