Function tokio_scoped::scope

pub fn scope<'a, F, R>(f: F) -> R where
    F: FnOnce(&mut Scope<'a>) -> R, 

Creates a Scope using the current tokio runtime and calls the scope method with the provided future

Example

#[tokio::main]
async fn main() {
    let mut v = String::from("Hello");
    tokio_scoped::scope(|scope| {
        // Use the scope to spawn the future.
        scope.spawn(async {
            v.push('!');
        });
    });
    // The scope won't exit until all spawned futures are complete.
    assert_eq!(v.as_str(), "Hello!");
}
