Trait guion::util::traitcast::Traitcast[−][src]

pub unsafe trait Traitcast<T, E>: Widget<E> where
    T: ?Sized,
    E: Env, {
    type DestTypeID: ?Sized + 'static;
    unsafe fn _traitcast_ref<'s>(
        senf: &'s dyn Widget<E>
    ) -> Result<&'s T, GuionError<E>> { ... }

    unsafe fn _try_traitcast_ref<'s>(
        senf: &'s dyn Widget<E>
    ) -> Result<&'s T, ()> { ... }
}

Trait to secure Traitcasting, generally implemented by macro

  • Always implemented on dyn Widget<E>
  • T is the destination dyn Trait to which should be traitcasted
  • DestTypeID must be the same type as T, but with ’static lifetimes. Used to retrieve TypeID
