Expand description
Supports conversion to Any
. Traits to be extended by impl_downcast!
must extend Downcast
.
Required Methods§
sourcefn into_any(self: Box<Self>) -> Box<dyn Any>
fn into_any(self: Box<Self>) -> Box<dyn Any>
Convert Box<dyn Trait>
(where Trait: Downcast
) to Box<dyn Any>
. Box<dyn Any>
can
then be further downcast
into Box<ConcreteType>
where ConcreteType
implements Trait
.
sourcefn into_any_rc(self: Rc<Self>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any>
Convert Rc<Trait>
(where Trait: Downcast
) to Rc<Any>
. Rc<Any>
can then be
further downcast
into Rc<ConcreteType>
where ConcreteType
implements Trait
.
sourcefn as_any(&self) -> &dyn Any
fn as_any(&self) -> &dyn Any
Convert &Trait
(where Trait: Downcast
) to &Any
. This is needed since Rust cannot
generate &Any
’s vtable from &Trait
’s.
sourcefn as_any_mut(&mut self) -> &mut dyn Any
fn as_any_mut(&mut self) -> &mut dyn Any
Convert &mut Trait
(where Trait: Downcast
) to &Any
. This is needed since Rust cannot
generate &mut Any
’s vtable from &mut Trait
’s.
