func TracerStreamServerInterceptor

func TracerStreamServerInterceptor(srv interface{}, ss grpc.ServerStream, info *grpc.StreamServerInfo, handler grpc.StreamHandler) (err error)

TracerStreamServerInterceptor will perform xray tracing for each stream RPC call

to pass in parent xray segment id and trace id, set the metadata keys with:

x-amzn-seg-id = parent xray segment id, assign value to this key via metadata.MD
x-amzn-tr-id = parent xray trace id, assign value to this key via metadata.MD

how to set metadata at client side?

ctx := context.Background()
md := metadata.Pairs("x-amzn-seg-id", "abc", "x-amzn-tr-id", "def")
ctx = metadata.NewOutgoingContext(ctx, md)
