Introduction

Rust achieves multi-threading through asynchronous programming.

Executing Functions with Multiple Threads

fn function_name() {
    ...
}

fn main() {
    let thread_variable_1 = spawn(function_name);
    let thread_variable_2 = spawn(function_name);
    
    // Wait for the child threads to finish executing before exiting the program
    thread_variable_1.join().unwrap();
    thread_variable_2.join().unwrap();
}

Implementing with External Packages

Importing Dependencies

[dependencies]
async-std = { version = "1.12.0", features = ["attributes"] }

async fn function_name() {
    ...
    sleep(Duration::from_millis(500)).await;
}

#[async_std::main]
async fn main() {
    let thread_variable = spawn(function_name());
    
    // Wait for the child threads to finish executing before exiting the program
    thread_variable.await;
    function_name().await;
}

Done
