package noop

import "go.opentelemetry.io/otel/trace/noop"

Package noop provides an implementation of the OpenTelemetry trace API that produces no telemetry and minimizes used computation resources.

Using this package to implement the OpenTelemetry trace API will effectively disable OpenTelemetry.

This implementation can be embedded in other implementations of the OpenTelemetry trace API. Doing so will mean the implementation defaults to no operation for methods it does not implement.

Types ¶

type Span ¶

type Span struct {
	embedded.Span
	// contains filtered or unexported fields
}

Span is an OpenTelemetry No-Op Span.

func (Span) AddEvent ¶

func (Span) AddEvent(string, ...trace.EventOption)

AddEvent does nothing.

func (Span) AddLink ¶

func (Span) AddLink(trace.Link)

AddLink does nothing.

func (Span) End ¶

func (Span) End(...trace.SpanEndOption)

End does nothing.

func (Span) IsRecording ¶

func (Span) IsRecording() bool

IsRecording always returns false.

func (Span) RecordError ¶

func (Span) RecordError(error, ...trace.EventOption)

RecordError does nothing.

func (Span) SetAttributes ¶

func (Span) SetAttributes(...attribute.KeyValue)

SetAttributes does nothing.

func (Span) SetName ¶

func (Span) SetName(string)

SetName does nothing.

func (Span) SetStatus ¶

func (Span) SetStatus(codes.Code, string)

SetStatus does nothing.

func (Span) SpanContext ¶

func (s Span) SpanContext() trace.SpanContext

SpanContext returns an empty span context.

func (Span) TracerProvider ¶

func (Span) TracerProvider() trace.TracerProvider

TracerProvider returns a No-Op TracerProvider.

type Tracer ¶

type Tracer struct{ embedded.Tracer }

Tracer is an OpenTelemetry No-Op Tracer.

func (Tracer) Start ¶

func (t Tracer) Start(ctx context.Context, _ string, _ ...trace.SpanStartOption) (context.Context, trace.Span)

Start creates a span. The created span will be set in a child context of ctx and returned with the span.

If ctx contains a span context, the returned span will also contain that span context. If the span context in ctx is for a non-recording span, that span instance will be returned directly.

type TracerProvider ¶

type TracerProvider struct{ embedded.TracerProvider }

TracerProvider is an OpenTelemetry No-Op TracerProvider.

func NewTracerProvider ¶

func NewTracerProvider() TracerProvider

NewTracerProvider returns a TracerProvider that does not record any telemetry.

func (TracerProvider) Tracer ¶

func (TracerProvider) Tracer(string, ...trace.TracerOption) trace.Tracer

Tracer returns an OpenTelemetry Tracer that does not record any telemetry.
