 ### Capturing references in move contexts
 
-Rust doesn't allow moving fields out of references. As a result, in the case of move closures, when values accessed through a shared references are moved into the closure body, the compiler, instead of moving the values out of the reference, would reborrow the data.

 ### `Box` vs other `Deref` implementations

+The implementation of the [`Deref`] trait for [`Box`] is treated differently from other `Deref` implementations, as it is considered a special entity.
 
 For example, let us look at examples involving `Rc` and `Box`. The `*rc` is desugared to a call to the trait method `deref` defined on `Rc`, but since `*box` is treated differently by the compiler, the compiler is able to do precise capture on contents of the `Box`.

 #### Non `move` closure
 
 In a non `move` closure, if the contents of the `Box` are not moved into the closure body, the contents of the `Box` are precisely captured.
