public final class Span extends GeneratedMessageV3 implements SpanOrBuilder
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.

public TruncatableString getDisplayName()
Required. A description of the span's operation (up to 128 bytes).

the same display name within an application and at the same call point.
This makes it easier to correlate spans in different traces.
