Crate predisposition 

Three-valued boolean types with different predispositions for the unknown case.

This crate provides three enum types that extend bool with a third variant representing an unknown or unspecified value. Each type differs in how it resolves that third variant:

• OptimisticBool assumes true when uncertain.
• PessimisticBool assumes false when uncertain.
• UncertainBool makes no assumption; behaves exactly like Option<bool>.

Enums
