pub trait TypeData: Downcast + Send + Sync {
fn clone_type_data(&self) -> Box<dyn TypeData + 'static, Global>;
}Expand description
A trait for types generated by the #[reflect_trait] attribute macro.
Required Methods
fn clone_type_data(&self) -> Box<dyn TypeData + 'static, Global>
Implementations
impl dyn TypeData + 'static
impl dyn TypeData + 'static
pub fn is<__T>(&self) -> bool where
__T: TypeData,
pub fn is<__T>(&self) -> bool where
__T: TypeData,
Returns true if the trait object wraps an object of type __T.
pub fn downcast<__T>(
self: Box<dyn TypeData + 'static, Global>
) -> Result<Box<__T, Global>, Box<dyn TypeData + 'static, Global>> where
__T: TypeData,
pub fn downcast<__T>(
self: Box<dyn TypeData + 'static, Global>
) -> Result<Box<__T, Global>, Box<dyn TypeData + 'static, Global>> where
__T: TypeData,
Returns a boxed object from a boxed trait object if the underlying object is of type
__T. Returns the original boxed trait if it isn’t.
pub fn downcast_rc<__T>(
self: Rc<dyn TypeData + 'static>
) -> Result<Rc<__T>, Rc<dyn TypeData + 'static>> where
__T: TypeData,
pub fn downcast_rc<__T>(
self: Rc<dyn TypeData + 'static>
) -> Result<Rc<__T>, Rc<dyn TypeData + 'static>> where
__T: TypeData,
Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of
type __T. Returns the original Rc-ed trait if it isn’t.
pub fn downcast_ref<__T>(&self) -> Option<&__T> where
__T: TypeData,
pub fn downcast_ref<__T>(&self) -> Option<&__T> where
__T: TypeData,
Returns a reference to the object within the trait object if it is of type __T, or
None if it isn’t.
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T> where
__T: TypeData,
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T> where
__T: TypeData,
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn’t.
