    Interface Span

    Span represents a logical unit of work as part of a broader Trace. Examples of span might include remote procedure calls or a in-process function calls to sub-components. A Trace has a single, top-level "root" Span that in turn may have zero or more child Spans, which in turn may have children.

    interface Span {
        addLink(context: SpanContext, attributes?: Object): void;
        addLink(link: { attributes?: Object; context: SpanContext }): void;
        addLinks(links: { attributes?: Object; context: SpanContext }[]): void;
        context(): SpanContext;
    }
