What's the normal way of dealing with "global" state in a Rust program using tokio? Or, to ask a more specific question expressing what I think I want: is there a way to teach the borrow checker that an object has a lifetime longer than the tokio event loop? /cc @ManishEarth

You could make a "proper" global using thread local state or lazy_static

You can otherwise specify the right outlives lifetime bounds but I'm not sure where they'd go, i'd need an example of what you'd want to do

I don't think I want a proper global since the "global" is set up differently in the running bot versus the tests. And it's state that's used in a bunch of functions. (That said, what I'm thinking of might fail on mutable vs. non-mutable borrows anyway... need to look.)

How are you starting the tokio event loop?

let mut core = Core::new().unwrap(); let mut irc_state = IRCState::new(ghtype, handle); let ircstream = ...; core.run(ircstream); ... but I could change it.

So what's the actual error message you get? Core::run doesn't require `static bounds on the future you hand it.

The actual error messages are from the borrow checker, about lifetimes of references in closures involved in an additional call to post to the Tokio event loop (handle.spawn(...)).
