Index

• func Error(span opentracing.Span, err error)
• func Errorf(span opentracing.Span, format string, a ...interface{})
• func Failure(span opentracing.Span)
• func NewSpan(ctx context.Context, tracer opentracing.Tracer, name string) (context.Context, opentracing.Span)

Functions

func Error

func Error(span opentracing.Span, err error)

Error logs error

func Errorf

func Errorf(span opentracing.Span, format string, a ...interface{})

Errorf logs error

func Failure

func Failure(span opentracing.Span)

Failure marks the current request as a failure

func NewSpan

func NewSpan(ctx context.Context, tracer opentracing.Tracer, name string) (context.Context, opentracing.Span)

NewSpan pulls the span out of the context, creates a new child span, and updates the context callers must call span.Finish() when done important: the context must contain a span, otherwise you'll see a nilpointer panic here.
