By-value memory storage without by-value memory access.
Guests allow one to have reading and writing access whilst garunteeing that the memory is handed on to the next owner after usage.
Some example types are as follows:
- Read access:
Arc<Guest<T>> - Write access:
Arc<Mutex<Guest<T>>> - Read and Write access:
Arc<RwLock<Guest<T>>>
Some example callbacks could be:
- Just dropping:
std::mem::drop - Sending through a channel:
move |last| sender.send(last).unwrap() - Setting a value:
|last| capture = last
