impl<T> Any for T
where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

§

impl As for U

§

fn as_<T>(self) -> T
where T: CastFrom,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_:: can be used in the same way as T as U for numeric conversions. Read more

§

impl<T> Downcast for T
where T: AsAny + ?Sized,

§

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

Source §

impl<T, U> Into for T
where U: From<T>,

Source §

fn into(self) -> U

Calls U::from(self).
