How to Build a Task Queue in Rust

Build a task queue in Rust by using trpl::spawn_task to enqueue work and trpl::join or handle.await to process results concurrently.

use std::time::Duration;

fn main() {
    trpl::block_on(async {
        let handle = trpl::spawn_task(async {
            for i in 1..10 {
                println!("Task {i} running");
                trpl::sleep(Duration::from_millis(500)).await;
            }
        });

        trpl::join(
            async { println!("Other work"); },
            async { handle.await.unwrap(); }
        ).await;
    });
}

A task queue lets your program handle multiple jobs at once without waiting for each one to finish before starting the next. Think of it like a restaurant kitchen where the head chef assigns orders to different cooks so meals get ready faster. You use this pattern when you have many independent tasks, like downloading files or processing data, that can run simultaneously.
