Enum Object

pub enum Object {
    Literal(Literal),
    Function(Function),
    NativeFunction(NativeFunction),
    Class(Rc<RefCell<Class>>),
    Instance(Rc<RefCell<Instance>>),
}

Represents an object that can be stored in a variable or returned from a function. This is an enum that wraps all the possible types of values in the language.

Variants

Converts to this type from the input type.

impl From<Function> for Object

fn from(value: Function) -> Self

Converts to this type from the input type.

impl From<Instance> for Object

fn from(value: Instance) -> Self

Converts to this type from the input type.

impl From<Literal> for Object

fn from(literal: Literal) -> Self

Converts to this type from the input type.

impl From<NativeFunction> for Object

fn from(value: NativeFunction) -> Self

Converts to this type from the input type.

impl From<Rc<RefCell<Class>>> for Object

fn from(value: Rc<RefCell<Class>>) -> Self

Converts to this type from the input type.

impl From<Rc<RefCell<Instance>>> for Object

fn from(value: Rc<RefCell<Instance>>) -> Self

Converts to this type from the input type.

fn from(boolean: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Object

fn from(number: f64) -> Self

Converts to this type from the input type.

impl Mul for Object

type Output = Option<Object>

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl Neg for Object

type Output = Option<Object>

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl Not for Object

type Output = Option<Object>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for Object

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

Tests for self and other values to be equal, and is used by ==.

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

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

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for Object

type Output = Option<Object>

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.
