pub struct ClassStruct<T>where
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>>§
pub fn has_property(&self, property_name: &str, type_: Option<Type>) -> bool
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.
pub fn property_type(&self, property_name: &str) -> Option<Type>
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.
pub fn find_property(&self, property_name: &str) -> Option<ParamSpec>
pub fn find_property(&self, property_name: &str) -> Option<ParamSpec>
Get the ParamSpec
of the property property_name
of this object class.
pub fn list_properties(&self) -> PtrSlice<ParamSpec>
pub fn list_properties(&self) -> PtrSlice<ParamSpec>
Return all ParamSpec
of the properties of this object class.
pub fn type_(&self) -> Type
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.
pub fn upcast_ref<U>(&self) -> &Class<U>where
U: IsClass,
T: IsA<U>,
pub fn upcast_ref<U>(&self) -> &Class<U>where U: IsClass, T: IsA<U>,
Casts this class to a reference to a parent type’s class.
pub fn upcast_ref_mut<U>(&mut self) -> &mut Class<U>where
U: IsClass,
T: IsA<U>,
pub fn upcast_ref_mut<U>(&mut self) -> &mut Class<U>where U: IsClass, T: IsA<U>,
Casts this class to a mutable reference to a parent type’s class.
pub fn downcast_ref<U>(&self) -> Option<&Class<U>>where
U: IsClass + IsA<T>,
pub fn downcast_ref<U>(&self) -> Option<&Class<U>>where U: IsClass + 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.
pub fn downcast_ref_mut<U>(&mut self) -> Option<&mut Class<U>>where
U: IsClass + IsA<T>,
pub fn downcast_ref_mut<U>(&mut self) -> Option<&mut Class<U>>where U: IsClass + 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.
