Types

type IDGenerator

type IDGenerator struct{}

IDGenerator is a trace ID generator.

func NewIDGenerator

func NewIDGenerator() *IDGenerator

NewIDGenerator returns a new IDGenerator.

func (*IDGenerator) NewIDs

func (id *IDGenerator) NewIDs(ctx context.Context) (traceID trace.TraceID, spanID trace.SpanID)

NewIDs creates and returns a new trace and span ID.

func (*IDGenerator) NewSpanID

func (id *IDGenerator) NewSpanID(ctx context.Context, traceID trace.TraceID) (spanID trace.SpanID)

NewSpanID returns an ID for a new span in the trace with traceID.

type TracerProvider

type TracerProvider struct {
	*sdkTrace.TracerProvider
}

TracerProvider is a wrapper around sdkTrace.TracerProvider.

func New

func New() *TracerProvider

New returns a new and configured TracerProvider, which has no SpanProcessor.

In default the returned TracerProvider is configured with: - a ParentBased(AlwaysSample) Sampler; - a unix nano timestamp and random umber based IDGenerator; - the resource.Default() Resource; - the default SpanLimits.

The passed opts are used to override these default values and configure the returned TracerProvider appropriately.
