Functions

func Translate

func Translate(provider types.TraceProvider, rootDepth types.Depth) types.TraceProvider

Translate returns a new TraceProvider that translates any requested positions before passing them on to the specified provider. The translation is done such that the root node for provider is at rootDepth.
