Types ¶
type Extractor ¶
Extractor is a tool specification which define how to extract trace parent context from propagation context
type Injector ¶
Injector is a tool specification which define how to inject trace context into propagation context
type SpanContext ¶
type SpanContext struct {
TraceID string `json:"trace_id"`
ParentSegmentID string `json:"parent_segment_id"`
ParentService string `json:"parent_service"`
ParentServiceInstance string `json:"parent_service_instance"`
ParentEndpoint string `json:"parent_endpoint"`
AddressUsedAtClient string `json:"address_used_at_client"`
ParentSpanID int32 `json:"parent_span_id"`
Sample int8 `json:"sample"`
Valid bool `json:"valid"`
CorrelationContext map[string]string `json:"correlation_context"`
}
SpanContext defines propagation specification of SkyWalking
