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