pct property
Pct is how much of the run is done, 0 to 100. THE KEY IS ABSENT when progress is indeterminate — a run nobody can estimate is not a run that has done nothing, and rendering the second for the first is the mistake this omission exists to make impossible. Read phase before reaching for it.
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? pct;
