type Span struct {

	// the same `trace_id`. The ID is a 16-byte array. An ID with all zeroes

	//
	// This field is semantically required. Receiver should generate new
	// random trace_id if empty or invalid trace_id was received.

	// This field is required.
	TraceID string `protobuf:"bytes,1,opt,name=traceID,proto3" json:"traceID,omitempty"`
	// A unique identifier for a span within a trace, assigned when the span
	// is created. The ID is an 8-byte array. An ID with all zeroes is considered
	// invalid.
	//
	// This field is semantically required. Receiver should generate new
	// random span_id if empty or invalid span_id was received.
	//
	// This field is required.
	SpanID string `protobuf:"bytes,2,opt,name=spanID,proto3" json:"spanID,omitempty"`

	// field must be empty. The ID is an 8-byte array.

	// end_time_unix_nano is the end time of the span. On the client side, this is the time
	// kept by the local machine where the span execution ends. On the server side, this
	// is the time when the server application handler stops running.
	// Value is UNIX Epoch time in nanoseconds since 00:00:00 UTC on 1 January 1970.
	//
	// This field is semantically required and it is expected that end_time >= start_time.
	EndTimeUnixNano uint64 `protobuf:"fixed64,5,opt,name=endTimeUnixNano,proto3" json:"endTimeUnixNano,omitempty"`
	// A description of the span's operation.
	//
	// For example, the name can be a qualified method name or a file name
	// and a line number where the operation is called. A best practice is to use
	// the same display name at the same call point in an application.
	// This makes it easier to correlate spans in different traces.
	//
	// This field is semantically required to be set to non-empty string.
	// When null or empty string received - receiver may use string "name"
	// as a replacement. There might be smarted algorithms implemented by
	// receiver to fix the empty span name.
	//
	// This field is required.
