Function create_and_spawn 

pub fn create_and_spawn<G>() -> Result<(JoinHandle<Result<()>>, I2o2Handle<G>)>
where
    G: Send + 'static,

Create a new I2o2Scheduler and I2o2Handle pair backed by io_uring and spawn the scheduler in a background worker thread.

This will use the default settings for the scheduler, you can optionally use the builder to customise the ring behaviour.

NOTE: The scheduler cannot be sent across threads.

Example

let (scheduler_handle, handle) = i2o2::create_and_spawn::<()>()?;

// ... do work
