rust armanazi thread spawning join

To spawn a new thread in Rust and join it, you can use the std::thread module. First, import the module with use std::thread;. Then, you can use the thread::spawn function to create a new thread and pass it a closure containing the code you want to run in the new thread. Finally, you can use the join method on the JoinHandle returned by thread::spawn to wait for the thread to finish execution.

Here's an example code snippet that demonstrates the process:

use std::thread;

fn main() {
    // Spawn a new thread
    let handle = thread::spawn(|| {
        // Code to be executed in the new thread
        println!("Hello from the spawned thread!");
    });

    // Wait for the spawned thread to finish execution
    handle.join().expect("Failed to join the thread!");
}

In this example, the closure passed to thread::spawn simply prints a message. The handle.join() call waits for the thread to complete, and the expect method is used to handle any potential errors that may occur during the join process.

Keep in mind that the order in which threads execute is not guaranteed, so the output from the main thread and the spawned thread may be interleaved.
