Struct GoalEvaluation

Source 
pub struct GoalEvaluation<I>
where
    I: Interner,
{
    pub certainty: Certainty,
    pub has_changed: HasChanged,
    pub stalled_on: Option<GoalStalledOn<I>>,
}
Expand description

The result of evaluating a goal.

Fields§

§certainty: Certainty§has_changed: HasChanged§stalled_on: Option<GoalStalledOn<I>>

If the Certainty was Maybe, then keep track of whether the goal has changed before rerunning it.
