/**
 * Indicates that the return value of the annotated method must be used. An error is triggered when
 * one of these methods is called but the result is not used.
 *
 * {@code @CheckReturnValue} may be applied to a class or package to indicate that all methods in
 * that class (including indirectly; that is, methods of inner classes within the annotated class)
 * or package must have their return values used. For convenience, we provide an annotation, {@link
 * CanIgnoreReturnValue}, to exempt specific methods or classes from this behavior.
