Functions

func ClientUnary

func ClientUnary() grpc.UnaryClientInterceptor

ClientUnary adds spans + propagation for outbound gRPC.

func Middleware

func Middleware(service string, l *logger.Loggerx) func(http.Handler) http.Handler

Middleware wraps handlers with otelhttp and injects trace_id into ctx for logger.

func ServerUnary

func ServerUnary(l *logger.Loggerx) grpc.UnaryServerInterceptor

ServerUnary returns an interceptor that both creates spans and injects trace_id for logger.

func Start

func Start(ctx context.Context, opt Options) (func(context.Context) error, error)

func Transport

func Transport(base http.RoundTripper) http.RoundTripper

Transport wraps any RoundTripper so outbound HTTP gets spans + propagation.
