There was a problem hiding this comment.
Actually, Glib doesn't depend on tokio, but many async crates do. For example, using reqwest in future on a GLib executor will panic because it needs some tokio-specific features. This is not obvious for beginners because it should be as simple as using async/await but sadly that's not true in reality.
