Struct ICoWWeak 

Source 
pub struct ICoWWeak<ITEM: Sized> { /* private fields */ }
Expand description

A independent from the ICoW instance, which is not binded to the lifetime of the main instance. The value contains a read-only weak reference to ITEM. If the weak reference become invalid, then a new copy will be obtained.

It should not be accessed from multiple threads simultaniously!
