	"go.opentelemetry.io/otel"
)

func main() {
	p := jaeger.Jaeger{}
	// register jaeger propagator
	otel.SetTextMapPropagator(p)
}
Output:

func (Jaeger) Extract

func (jaeger Jaeger) Extract(ctx context.Context, carrier propagation.TextMapCarrier) context.Context

Extract extracts a context from the carrier if it contains Jaeger headers.

func (Jaeger) Fields

Fields returns the Jaeger header key whose value is set with Inject.
