Trait ListModelExtManual Copy item path
Summary Source pub trait ListModelExtManual: IsA <ListModel > + Sized {
// Provided methods
fn snapshot (&self) -> Vec <Object > { ... }
fn iter <LT: IsA <Object >>(&self) -> ListModelIter<'_, LT> { ... }
}
Get an immutable snapshot of the container inside the ListModel
.
Any modification done to the returned container Vec
will not be
reflected on the ListModel
.
If T::static_type().is_a(self.item_type())
then it returns an iterator over the ListModel
elements,
else the types are not compatible and it panics.
§ Panics
Panics if T::static_type().is_a(self.item_type())
is not true.
This trait is not dyn compatible .
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
