Enum oso::PolarValue

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

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.

Variants

Integer(i64)

Float(f64)

String(String)

Boolean(bool)

Map(HashMap<String, PolarValue>)

List(Vec<PolarValue>)

Variable(String)

Instance(Instance)

Implementations

impl PolarValue

pub fn new_from_instance<T>(instance: T) -> Self

where T: Send + Sync + 'static,

Create a PolarValue::Instance from any type.

Trait Implementations

impl Clone for PolarValue

fn clone(&self) -> PolarValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PolarValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromPolar for PolarValue

fn from_polar(val: PolarValue) -> Result<Self>

impl PartialEq for PolarValue

fn eq(&self, other: &PolarValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToPolar for PolarValue

fn to_polar(self) -> PolarValue

Convert this value into a Polar value.
