}

TraceContext trace

func NewTraceContext

func NewTraceContext(name string, headers map[string][]string) *TraceContext

NewTraceContext new traceCtx

func (*TraceContext) SpanFinish

type TracerContext

type TracerContext interface {
	SpanFinish(span opentracing.Span)

	// SpanStart 开启子span
	SpanStart(name string) opentracing.Span

	// SpanInject 注入请求
	SpanInject(md metautils.NiceMD)
}
