Methods
impl dyn Resource
pub fn is<T: Resource>(&self) -> bool
Returns true if the boxed type is the same as T
pub fn downcast_ref<T: Resource>(&self) -> Option<&T>
Returns some reference to the boxed value if it is of type T, or
None if it isn't.
pub unsafe fn downcast_ref_unchecked<T: Resource>(&self) -> &T
Returns a reference to the boxed value, blindly assuming it to be of type T.
If you are not absolutely certain of T, you must not call this.
pub fn downcast_mut<T: Resource>(&mut self) -> Option<&mut T>
Returns some mutable reference to the boxed value if it is of type T, or
None if it isn't.
pub unsafe fn downcast_mut_unchecked<T: Resource>(&mut self) -> &mut T
Returns a mutable reference to the boxed value, blindly assuming it to be of type T.
If you are not absolutely certain of T, you must not call this.
impl dyn Resource
pub fn downcast<T: Resource>(self: Box<Self>) -> Result<Box<T>, Box<Self>>
Returns the boxed value if it is of type T, or Err(Self) if it isn't.
pub unsafe fn downcast_unchecked<T: Resource>(self: Box<Self>) -> Box<T>
Returns the boxed value, blindly assuming it to be of type T.
