Trait std::any::Any [−] [src]

pub trait Any: 'static + Reflect {
    fn get_type_id(&self) -> TypeId;
}

A type to emulate dynamic typing.

Every type with no non-'static references implements Any. See the module-level documentation for more details.

Required Methods

fn get_type_id(&self) -> TypeId

Unstable (get_type_id #27745)

: this method will likely be replaced by an associated static

Gets the TypeId of self.

Methods

impl Any + 'static

fn is<T>(&self) -> bool where T: Any

Returns true if the boxed type is the same as T

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

Returns some reference to the boxed value if it is of type T, or None if it isn't.

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

Returns some mutable reference to the boxed value if it is of type T, or None if it isn't.

impl Any + 'static + Send

fn is<T>(&self) -> bool where T: Any

Forwards to the method defined on the type Any.

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

Forwards to the method defined on the type Any.

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

Forwards to the method defined on the type Any.
