pub struct ScopeMark { /* private fields */ }Expand description
Where a scope stood, so a scoped Open … in … (or a declaration’s own implicit namespace) can be
wound back EXACTLY, without knowing what it pushed.
It saves the scope rather than an index into it because _root_.baz elaborates at the root: a
bracketed change may REMOVE frames as well as add them, and a high-water mark cannot restore
what was cleared. Two short Vec clones per command, against a whole elaboration.

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.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
