#[repr(C)]
pub struct ClassStruct<T: ObjectSubclass> { /* private fields */ }

Expand description

A basic class struct that does not store any additional data or virtual methods.

Methods from Deref<Target = Class<<T as ObjectSubclass>::Type>>

source

pub fn has_property(&self, property_name: &str, type_: Option<Type>) -> bool

Check if the object class has a property property_name of the given type_.

If no type is provided then only the existence of the property is checked.

source

pub fn property_type(&self, property_name: &str) -> Option<Type>

Get the type of the property property_name of this object class.

This returns None if the property does not exist.

source

pub fn find_property(&self, property_name: &str) -> Option<ParamSpec>

Get the ParamSpec of the property property_name of this object class.

source

pub fn list_properties(&self) -> PtrSlice<ParamSpec>

Return all ParamSpec of the properties of this object class.

source

pub fn type_(&self) -> Type

Get the type id for this class.

This is not equivalent to T::static_type() but is the type of the subclass of T where this class belongs to.

source

pub fn upcast_ref<U: IsClass>(&self) -> &Class where
T: IsA,

Casts this class to a reference to a parent type’s class.

source

pub fn upcast_ref_mut<U: IsClass>(&mut self) -> &mut Class where
T: IsA,

Casts this class to a mutable reference to a parent type’s class.

source

pub fn downcast_ref<U: IsClass>(&self) -> Option<&Class> where
U: IsA<T>,

Casts this class to a reference to a child type’s class or fails if this class is not implementing the child class.

source

pub fn downcast_ref_mut<U: IsClass>(&mut self) -> Option<&mut Class> where
U: IsA<T>,

Casts this class to a mutable reference to a child type’s class or fails if this class is not implementing the child class.

source

pub fn parent(&self) -> Option<ClassRef<'_, T>>

Gets the parent class struct, if any.
