Function spawn_local 

pub fn spawn_local<F, S>(
    future: F,
    scheduler: S,
) -> (Runnable, AsyncTask<F::Output>)
where
    F: Future + 'static,
    S: Fn(Runnable) + Send + Sync + 'static,

Available on crate features async-task and std only.

Spawn a local (non-Send) future with a custom scheduler using async_task.

This is similar to spawn but works with futures that are not Send. It uses async_task::spawn_local internally.

This function is only available when the std feature is enabled.
