rustHow to use a callback with a Rust thread?
Using a callback with a Rust thread is a great way to ensure that a task is completed before continuing with the main thread. To do this, you can use the thread::spawn
function to create a new thread and pass a closure as an argument. The closure will be executed in the new thread and can be used to call a callback when the task is finished.
Example code
use std::thread;
fn main() {
let handle = thread::spawn(|| {
// Do some work
// Call the callback when done
});
// Wait for the thread to finish
handle.join().unwrap();
}
Output example

Code explanation
thread::spawn
: This function creates a new thread and takes a closure as an argument. The closure will be executed in the new thread.handle.join().unwrap()
: This line waits for the thread to finish before continuing with the main thread.
