type TraceContext ¶
type TraceContext struct{}
TraceContext is a propagator that supports the W3C Trace Context format (https://www.w3.org/TR/trace-context/)
This propagator will propagate the traceparent and tracestate headers to guarantee traces are not broken. It is up to the users of this propagator to choose if they want to participate in a trace by modifying the traceparent header and relevant parts of the tracestate header containing their proprietary information.
func (TraceContext) Extract ¶
func (tc TraceContext) Extract(ctx context.Context, carrier propagation.TextMapCarrier) context.Context
Extract reads tracecontext from the carrier into a returned Context.
The returned Context will be a copy of ctx and contain the extracted tracecontext as the remote SpanContext. If the extracted tracecontext is invalid, the passed ctx will be returned directly instead.
func (TraceContext) Fields ¶
func (tc TraceContext) Fields() []string
Fields returns the keys who's values are set with Inject.
func (TraceContext) Inject ¶
func (tc TraceContext) Inject(ctx context.Context, carrier propagation.TextMapCarrier)
Inject set tracecontext from the Context into the carrier.
