fragile 0.3.0

Provides wrapper types for sending non-send values to other threads.


This library provides wrapper types that permit sending non Send types to other threads and use runtime checks to ensure safety.

It provides two types: Fragile<T> and Sticky<T> which are similar in nature but have different behaviors with regards to how destructors are executed. The former will panic if the destructor is called in another thread, the latter will temporarily leak the object until the thread shuts down.

use std::thread;

// creating and using a fragile object in the same thread works
let val = Fragile::new(true);
assert_eq!(*val.get(), true);

// once send to another thread it stops working
thread::spawn(move || {
