fn downcast_ref(&self) -> Result<&T, TypeMismatch>
fn downcast_mut(&mut self) -> Result<&mut T, TypeMismatch>
fn downcast(self: Box<Self>) -> Result<Box<T>, DowncastError<Box<Self>>>

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.
