Class TraceSpan (0.23.0)

A span represents a single timed event within a trace. Spans can be nested and form a trace tree. Often, a trace contains a root span that describes the end-to-end latency of an operation and, optionally, one or more subspans for its suboperations. Spans do not need to be contiguous. There may be gaps between spans in a trace.

Distinguishes between spans generated in a particular context. For example, two spans with the same name may be distinguished using RPC_CLIENT and RPC_SERVER to identify queueing latency associated with the span.

Start time of the span in nanoseconds from the UNIX epoch.

ID of the parent span, if any. Optional.
