Hands-On Functional Programming in Rust

Using thread concurrency

Rust threads have the following features:

• Share memory
• Share resources, such as files or sockets
• Tend to be thread-safe
• Support inter-thread messaging
• Are platform-independent

For the preceding reasons, we suggest that Rust threads are better suited to most concurrency use cases than subprocesses. If you want to distribute computation, circumvent a blocking operation, or otherwise utilize concurrency for your application—use threads.

To show the thread pattern, we can re-implement the preceding examples. Here are three children threads:

use std::{thread,time};use std::process;extern crate thread_id;fn main() {   for _ in 0..3 {      thread::spawn(|| {         let t = time::Duration::from_millis(1000);         loop { println!("child thread ...
