impl dyn SimCallback
pub fn is<__T: SimCallback>(&self) -> bool
Returns true if the trait object wraps an object of type __T.
pub fn downcast<__T: SimCallback>(
self: Box<Self>
) -> Result<Box<__T>, Box<Self>>
self: Box<Self>
) -> Result<Box<__T>, Box<Self>>
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: SimCallback>(
self: Rc<Self>
) -> Result<Rc<__T>, Rc<Self>>
self: Rc<Self>
) -> Result<Rc<__T>, Rc<Self>>
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: SimCallback>(&self) -> Option<&__T>
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: SimCallback>(&mut self) -> Option<&mut __T>
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn't.
