Fields

• boundTopTerm :: !(NonceAppExpr t BaseBoolType)

  The outer term containing the binding (e.g., Ax.f(x))

• boundQuant :: !BoundQuant

  The type of quantifier that appears

• boundVar :: !(ExprBoundVar t tp)

  The variable that is bound Variables may be bound multiple times.

type QuantifierInfoMap t = Map (NonceAppExpr t BaseBoolType) (Some (QuantifierInfo t))

problemFeatures :: Simple Lens (CollectedVarInfo t) ProblemFeatures

Describes types of functionality required by solver based on the problem.

existQuantifiers :: Simple Lens (CollectedVarInfo t) (QuantifierInfoMap t)

forallQuantifiers :: Simple Lens (CollectedVarInfo t) (QuantifierInfoMap t)

Expressions appearing in the problem as existentially quantified when the problem is expressed in negation normal form. This is a map from the existential quantifier element to the info.
