Trait AnyExt 

pub trait AnyExt: Any {
    // Provided methods
    fn is<T: Any + ?Sized>(&self) -> bool { ... }
    fn downcast_ref<T: Any>(&self) -> Option<&T> { ... }
    fn downcast_mut<T: Any>(&mut self) -> Option<&mut T> { ... }
}

Extension of Any for using its methods directly on the value without dyn.

Provided Methods

fn is<T: Any + ?Sized>(&self) -> bool

Returns true if the this type is the same as T.

fn downcast_ref<T: Any>(&self) -> Option<&T>

Returns Some reference to this value if it’s of type T, or None otherwise.

fn downcast_mut<T: Any>(&mut self) -> Option<&mut T>

Returns Some mutable reference to this value if it’s of type T, or None otherwise.

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.
