This is a Rust package that basically provides 3 wrapper types. * UnsafeSend * UnsafeSync * UnsafeSendSync They can be used to force structs to be Send and/or Sync, which is unsafe of course.
```rustc use std::rc::Rc; use tokio;
...
let not_send = Rc::
assert!( notsend.strongcount() == 1, "We can't really send a reference counted pointer across threads unless it only has one reference." );
tokio::spawn(move || { println!("We found a number: {}", *not_send); }); ```
