 * A span represents a single operation within a trace. Spans can be
 * nested to form a trace tree. Often, a trace contains a root span
 * that describes the end-to-end latency, and one or more subspans for
 * its sub-operations.
 * A trace can also contain multiple root spans, or none at all.
 * Spans do not need to be contiguous. There might be
 * gaps or overlaps between spans in a trace.
