pub fn is<__T: BodyPart<N>>(&self) -> bool
Returns true if the trait object wraps an object of type __T
.
pub fn downcast<__T: BodyPart<N>>(
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_ref<__T: BodyPart<N>>(&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: BodyPart<N>>(&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.
