depth property
Depth is the deepest hop count actually reached. It is at most the depth asked for, and smaller when the walk ran out of edges first.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? depth;
