Enum oso::PolarValue[−][src]

pub enum PolarValue {
    Integer(i64),
    Float(f64),
    String(String),
    Boolean(bool),
    Map(HashMap<String, PolarValue>),
    List(Vec<PolarValue>),
    Variable(String),
    Instance(Instance),
}

Expand description

An enum of the possible value types that can be sent to/from Polar.

All variants except Instance represent types that can be used natively in Polar. Any other types can be wrapped using PolarValue::new_from_instance. If the instance has a registered Class, then this can be used from the policy too.
