Forever

A never-dropping data store

Defines the Forever struct, which provides immutable access to data that is Sync, Send, and is never dropped. You can think of it as an Arc with an always positive refcount.

Example:

fn main() {
    let a = Forever::new(7u); // 7u will never be dropped.
    let b = a.clone() // Same underlying data.

    spawn(proc() {
        println!("{}", *b); // 7
    });
}

lib.rs:

Shareable data that lasts forever, with no reference count.
