Types

type IDGenerator

type IDGenerator interface {
	SpanID(traceID model.TraceID) model.ID // Generates a new Span ID
	TraceID() model.TraceID                // Generates a new Trace ID
}

IDGenerator interface can be used to provide the Zipkin Tracer with custom implementations to generate Span and Trace IDs.

func NewRandom128

func NewRandom128() IDGenerator

NewRandom128 returns an ID Generator which can generate 128 bit trace and 64 bit span id's

func NewRandom64

func NewRandom64() IDGenerator

NewRandom64 returns an ID Generator which can generate 64 bit trace and span id's

func NewRandomTimestamped

func NewRandomTimestamped() IDGenerator

NewRandomTimestamped generates 128 bit time sortable traceid's and 64 bit spanid's.
