Methods from Deref<Target = Resource + 'static>
fn downcast<T>(
self: Box<Resource + 'static>
) -> Result<Box<T>, Box<Resource + 'static>> where
T: Resource,
self: Box<Resource + 'static>
) -> Result<Box<T>, Box<Resource + 'static>> where
T: Resource,
Returns the boxed value if it is of type T, or Err(Self) if it isn't.
unsafe fn downcast_unchecked<T>(self: Box<Resource + 'static>) -> Box<T> where
T: Resource,
T: Resource,
Returns the boxed value, blindly assuming it to be of type T.
If you are not absolutely certain of T, you must not call this.
fn is<T>(&self) -> bool where
T: Resource,
T: Resource,
Returns true if the boxed type is the same as T
fn downcast_ref<T>(&self) -> Option<&T> where
T: Resource,
T: Resource,
Returns some reference to the boxed value if it is of type T, or
None if it isn't.
unsafe fn downcast_ref_unchecked<T>(&self) -> &T where
T: Resource,
T: Resource,
