§fn as_<T>(self) -> Twhere
T: CastFrom<U>,
fn as_<T>(self) -> Twhere
T: CastFrom<U>,
Casts
self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read moreSource§impl<T> BorrowMut<T> for Twhere
