Spawning async tasks in GTK apps

I'm trying to spawn async tasks in a GTK app using GLib's MainContext::spawn. Questions:

• I'm not sure how to get MainContext of a GTK Application. I think Application should already have a MainContext, and I'm not sure if creating a new one is safe.

• In a task spawned by MainContext::spawn I'm not sure which async I/O function/traits I can use. I think I can use AsyncRead/AsyncWrite from futures but that's not documented.

• In a task I'm not sure how to spawn more tasks. Should I pass a copy of MainContext to my tasks and use it to spawn more tasks via the spawn method?

Any pointer on these would be appreciated.

For (1) use MainContext::default()

For (2) use stuff from "futures" or "gio" libs

"the futures crate is completely runtime-independent"

For (3) just do MainContext::default().spawn(...)
