Crate lagoon

Lagoon is a thread pool crate that aims to address many of the problems with existing thread pool crates.

Features

• Scoped jobs: Safely spawn jobs that have access to their parent scope!
• Job handles: Receive the result of a job when it finishes, or wait on it to finish!
• Global pool: A pay-for-what-you-use global thread pool that avoids dependencies fighting over resources!
• Customise thread attributes: Specify thread name, stack size, etc.

let pool = lagoon::ThreadPool::default();

// Spawn some jobs that notify us when they're finished
let jobs = (0..10)
    .map(|i| pool.run_recv(move || {
        println!("Hello! i = {}", i);
    }))
    .collect::<Vec<_>>();

// Wait for all jobs to finish
for job in jobs {
    job.join().unwrap();
}
