Function crayon::sched::scope

pub fn scope<'s, F, R>(func: F) -> Rwhere
    F: for<'r> FnOnce(&'r Scope<'s>) -> R + 's + Send,
    R: Send,

Create a “fork-join” scope s and invokes the closure with a reference to s. This closure can then spawn asynchronous tasks into s. Those tasks may run asynchronously with respect to the closure; they may themselves spawn additional tasks into s. When the closure returns, it will block until all tasks that have been spawned into s complete.
