    public static final class Span.Link.Builder extends GeneratedMessage.Builder<Span.Link.Builder> implements Span.LinkOrBuilder

A pointer from the current span to another span in the same trace or in a
different trace. For example, this can be used in batching operations,
where a single batch handler processes multiple requests from different
traces or when the handler receives a request from a different project.
