Detailed Description

Represents an edge in an X-Trace graph, i.e., a causal relationship between two events.

Deprecated:

With the deprecation of chainIds and edge directions, this class has little reason to exist, and will be replaced by an OpId object, or by a Metadata object, if we decide to allow edges between tasks.
