Detailed Description
Represents a single operation within a trace.
A span is the primary building block of a distributed trace. It represents a single operation and contains timing information, a name, attributes, and relationships to other spans. Spans form a tree structure through parent-child relationships, and can also form a hypergraph through links.
This structure is designed to be compatible with OpenTelemetry's span model.
