pub struct ComponentVTable<T: 'static> { /* private fields */ }Expand description
Holds untyped information for everything a component can do
Implementations§
Source§impl<T: Clone + ComponentValue> ComponentVTable<T>
impl<T: Clone + ComponentValue> ComponentVTable<T>
Sourcepub const fn construct(
path: &'static str,
attributes: fn(ComponentDesc) -> AttributeStoreGuard,
attributes_init: fn(ComponentDesc) -> AttributeStoreGuardMut,
) -> Self
pub const fn construct( path: &'static str, attributes: fn(ComponentDesc) -> AttributeStoreGuard, attributes_init: fn(ComponentDesc) -> AttributeStoreGuardMut, ) -> Self
Creates a new vtable of T without any additional bounds
Sourcepub const fn construct_external() -> Self
pub const fn construct_external() -> Self
Construct a vtable for a component where the name and attributes are not statically known.
Must be hydrated by ComponentRegistry

impl<T: 'static> ComponentVTable<T>
Sourcepub const unsafe fn erase(&'static self) -> &'static ComponentVTable<()>
pub const unsafe fn erase(&'static self) -> &'static ComponentVTable<()>
Erases the vtable
§Safety
The table fields must have the same layout for all T.
More specifically:
No fields whose size is dependent on T.
No fn-ptr fields whose arguments type layout or return value are dependent on self.
Box<T>, &T, *const T, *mut T and similar thin pointers are safe.
&mut T is unsafe due to pointer variance

then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
