Functions

func Detach

func Detach(ctx context.Context) context.Context

Detach returns a context without an associated span. This allows the creation of spans that are not children of the current span.

func RegisterObservers

func RegisterObservers(o ...Observer)

func StartSpan

func StartSpan(ctx context.Context, name string, tags ...tag.Tag) (context.Context, func())
