/**
 * Indicates a public API that can change at any time, and has no guarantee of API stability and
 * backward-compatibility.
 *
 * Usage guidelines:
 *
 * 

 *   This annotation is used only on public API. Internal interfaces should not use it.
 *   
After OpenCensus has gained API stability, this annotation can only be added to new API.
 *       Adding it to an existing API is considered API-breaking.
 *   
Removing this annotation from an API gives it stable status.
