Required Methods§

Ensure that self is same type as another fact or a subtype

Provided Methods§

Implementations§

Returns true if the trait object wraps an object of type __T.

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.

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.

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
