@Retention(value=RUNTIME) @Documented @Target(value={METHOD,TYPE}) public @interface SchedulerSupport
Constants are provided for instances from Schedulers as well as values for
not using a scheduler and a manually-specified scheduler.
Libraries providing their own values should namespace them with their base package name followed
by a colon (:) and then a human-readable name (e.g., com.example:ui-thread).
