func NewFromRequest(r *http.Request) *TraceOTel

NewFromRequest creates new TraceOTel object. Returns nil if tracer not found in request.

func (*TraceOTel) IsReceived

func (t *TraceOTel) IsReceived() bool

IsReceived tells whether trace data was received (parsed from a request) or a random one.

func (*TraceOTel) SetHeader

func (t *TraceOTel) SetHeader(headers http.Header)

SetHeader sets request headers according to the trace data. This function is dummy, as headers are set at client transport.

func (*TraceOTel) Span

func (t *TraceOTel) Span(r *http.Request) (*http.Request, string)

Span spans the existing trace data and puts that into the request. Does not change the input trace data.

func (*TraceOTel) SpanID

func (t *TraceOTel) SpanID() string

SpanID returns the span ID of the trace data.

func (*TraceOTel) String

func (t *TraceOTel) String() string

String makes a log string from trace data.

func (*TraceOTel) TraceID

func (t *TraceOTel) TraceID() string

TraceID returns the trace ID of the trace data.
