rustHow to detach a thread in Rust?

Threads in Rust can be detached using the detach() method on a JoinHandle instance. This method will return a Result<()> indicating whether the thread was successfully detached.

use std::thread;

let handle = thread::spawn(|| {
    println!("Hello from a thread!");
});

handle.detach();

The code above will create a new thread and detach it immediately.

1. use std::thread; - imports the thread module from the standard library.
2. let handle = thread::spawn(|| { - creates a new thread and stores a JoinHandle instance in the handle variable.
3. println!("Hello from a thread!"); - prints a message from the thread.
4. handle.detach(); - detaches the thread.
