type Tracer ¶ Uses

type Tracer struct {
    // contains filtered or unexported fields
}

Tracer represents a wrapper for OpenTracing that implements tracing.Tracer.

func NewTracer ¶ Uses

func NewTracer(tracer opentracing.Tracer) *Tracer

NewTracer returns a new instance of Tracer.

func (*Tracer) ExtractHTTPHeaders ¶ Uses

func (t *Tracer) ExtractHTTPHeaders(r *http.Request) (tracing.Span, context.Context)

ExtractHTTPHeaders reads the HTTP headers to derive incoming context.

func (*Tracer) InjectHTTPHeaders ¶ Uses

func (t *Tracer) InjectHTTPHeaders(r *http.Request)

InjectHTTPHeaders adds the required HTTP headers to pass context between nodes.

func (*Tracer) StartSpanFromContext ¶ Uses

func (t *Tracer) StartSpanFromContext(ctx context.Context, operationName string) (tracing.Span, context.Context)

StartSpanFromContext returns a new child span and context from a given context.
