Struct Instance

pub struct Instance { /* private fields */ }

Represents an instance of a class.

Fields

Fields are variables that are defined inside a class. They can be accessed by using the . operator after the instance name. Fields can be defined by using the = operator after the field name.

Methods

Methods are functions that are defined inside a class. They can be called on instances of the class. Methods can be called by using the () operator after the method name.

Implementations

impl Instance

pub fn get( &self, name: &Token, instance: &Object, ) -> Result<Object, RuntimeError>

Returns the value of the field with the given name. If the field is not defined, it will return an error. If the field is not defined in this class, it will inherit the field from its superclass (if any).

pub fn set(&mut self, name: &Token, value: Object)

Sets the value of the field with the given name.

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Instance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instance

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

Formats the value using the given formatter.

impl Display for Instance

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

Formats the value using the given formatter.

impl From<&Rc<RefCell<Class>>> for Instance

fn from(value: &Rc<RefCell<Class>>) -> 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 PartialEq for Instance

fn eq(&self, _: &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.
