Types

type Propagation

type Propagation struct {
	TraceID      string
	ParentID     string
	TraceContext map[string]interface{}
}

func UnmarshalTraceContext

func UnmarshalTraceContext(header string) (*Propagation, error)

func UnmarshalTraceContextV1

func UnmarshalTraceContextV1(header string) (*Propagation, error)

UnmarshalTraceContextV1 takes the trace header, stripped of the version string, and returns the component parts. Trace ID and Parent ID are both required. If either is absent a nil trace header will be returned.

type PropagationError

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

func (*PropagationError) Error

func (p *PropagationError) Error() string
