Types

type Transport

type Transport struct {
	// Tracer is the OTel tracer to use. Defaults to the global tracer.
	Tracer trace.Tracer
	// Propagator is the text map propagator. Defaults to the global propagator.
	Propagator propagation.TextMapPropagator
	// Base is the underlying transport.
	Base http.RoundTripper
	// SpanNameFormatter formats the span name from the request.
	// Default: "HTTP <METHOD>"
	SpanNameFormatter func(req *http.Request) string
}

Transport wraps an http.RoundTripper with OpenTelemetry tracing. It creates a child span for each request and propagates trace context headers.

func (*Transport) RoundTrip

func (t *Transport) RoundTrip(req *http.Request) (*http.Response, error)

RoundTrip creates an OTel span, injects trace context, and forwards the request.
