This library provides wrapper types that permit sending non Send types to other threads and use runtime checks to ensure safety.
It provides the Fragile<T>, Sticky<T> and SemiSticky<T> types which are similar in nature but have different behaviors with regards to how destructors are executed. The Fragile<T> will panic if the destructor is called in another thread, Sticky<T> will temporarily leak the object until the thread shuts down. SemiSticky<T> is a compromise of the two. It behaves like Sticky<T> but it avoids the use of thread local storage if the type does not need Drop.
use std::thread; // creating and using a fragile object in the same thread works let val = Fragile::new(true); assert_eq!(*val.get(), true); assert!(val.try_get().is_ok()); // once send to another thread it stops working thread::spawn(move || { assert!(val.try_get().is_err()); }).join() .unwrap();
