// Provided methods
unsafe fn downcast_ref_unchecked<T: Any>(&self) -> &T { ... }

unsafe fn downcast_unchecked<T: Any>(self: Box<Self>) -> Box<T> { ... }
}Expand description
An extension trait for unchecked downcasting of trait objects.
Provided Methods§
Sourceunsafe fn downcast_ref_unchecked<T: Any>(&self) -> &T
unsafe fn downcast_ref_unchecked<T: Any>(&self) -> &T
Returns a reference to the contained value, assuming that it is of type T.
§Warning
If you are not absolutely certain of T you should not call this!
Sourceunsafe fn downcast_mut_unchecked<T: Any>(&mut self) -> &mut T
unsafe fn downcast_mut_unchecked<T: Any>(&mut self) -> &mut T
Returns a mutable reference to the contained value, assuming that it is of type T.
§Warning
If you are not absolutely certain of T you should not call this!
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
