Documentation

Overview

Package tracing complements the opentracing go package.

Index

• func SpanContextFromBinary(scBinary []byte) (opentracing.SpanContext, error)

Functions

func SpanContextFromBinary

func SpanContextFromBinary(scBinary []byte) (opentracing.SpanContext, error)

SpanContextFromBinary unmarshals the given byte array containing the SpanContext in binary format. Returns a new SpanContext instance using the global tracer.

func SpanContextToBinary

func SpanContextToBinary(sc opentracing.SpanContext) ([]byte, error)

SpanContextToBinary marshals the given SpanContext to a binary format using the global tracer. Returns either the in-memory bytes array or an error.

func StartSpanWithContext

func StartSpanWithContext(ctx context.Context, operationName string, opts ...opentracing.StartSpanOption) (opentracing.Span, context.Context)

StartSpanWithContext creates a new span and returns a context containing it. In contrast to opentracing.StartSpanFromContext(), this function does not take existing span from `ctx` as a ChildOfRef.
