Struct debris_llir::debris_object::ObjectRef

pub struct ObjectRef(Rc<DebrisObject<dyn ObjectPayload>>);

This struct is used to pass objects around

Objects references are read-only, so values that can be modified must be declared in a cell.

Tuple Fields

0: Rc<DebrisObject<dyn ObjectPayload>>

Implementations

impl ObjectRef

pub fn from_payload<T: ObjectPayload>(ctx: &TypeContext, value: T) -> Self

Methods from Deref<Target = DebrisObject<dyn ObjectPayload>>

pub fn get_property( &self, ctx: &TypeContext, ident: &Ident ) -> Option<ObjectRef>

Tries to get a property that belongs to this object

First tries to retrieve the property from its payload. If that fails, tries to retrieve the property from its class.

pub fn downcast_payload<T: ObjectPayload>(&self) -> Option<&T>

Converts the payload into its original type

Returns None if the downcast is not possible

pub fn downcast_class(&self) -> Option<ClassRef>

Helper function for downcasting the payload into a class

Trait Implementations

impl Clone for ObjectRef

fn clone(&self) -> ObjectRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectRef

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

Formats the value using the given formatter.

impl Deref for ObjectRef

type Target = DebrisObject<dyn ObjectPayload>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for ObjectRef

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

Formats the value using the given formatter.

impl<T: ObjectPayload> From<DebrisObject<T>> for ObjectRef

fn from(object: DebrisObject<T>) -> Self

Converts to this type from the input type.

impl PartialEq for ObjectRef

fn eq(&self, other: &ObjectRef) -> 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 ValidReturnType for ObjectRef

fn into_result( self, _ctx: &mut FunctionContext<'_, '_, '_> ) -> Option<LangResult<ObjectRef>>

impl Eq for ObjectRef
