Hello,
I've updated my sample code to reflect what I'll do in my main program.
I put it back on the list because it can help as a pattern to manage a
tree of polymorph object.
It compile and works.
I have some question too because I'm not sure I've done it the right way:
* I cross the tree
I try to implement a sort of zoom UI. The UI components are organized in
a tree. To update a component in the UI I use a search function
(match_fn() in the example) which take a closure as search criteria and
if it returns something I use an update function (test_mutable) with a
closure to do
),
None = {},
}
}
}
#[main]
fn main() {
TestMatchBorrow();
}

Very good idea. The vector don't have to be modified so it'll work.

I have the same type of errors in my code plus other error when the
trait can't be found like type `MyType` does not implement any method in

This code where compiling last week.

something like

I can't speculate on your encode error without seeing it.
