First, sorry for my English, it isn’t my mother language!
I’m learning Rust (very interesting), and I had a problem with boxed closure.
My goal is to play with kind of “actor”, that can run a closure from time to time, in a thread.
Here I have a working version of it, without thread : http://is.gd/aFJJcr. The Run struct is the “actor”, and own a closure. So for that, the closure is boxed (to be Sized and on the heap).
I want this closure run in it’s own thread. Here is a try : http://is.gd/uP2VbQ. The idea is to put the closure in an Arc Mutex to be shareable and mutable between threads.
But I have this error:
<anon>:20:13: 20:17 error: cannot borrow immutable `Box` content as mutable <anon>:20 (f2)();
Can someone explain me this error? Because I don’t understand why the deref of the box is not mutable…
Thank you in advance,
