Threadpool provides a way to manage and execute tasks concurrently using a fixed number of worker threads. It allows you to submit tasks that will be executed by one of the available worker threads, providing an efficient way to parallelize work across multiple threads.
Maintaining a pool of threads over creating a new thread for each task has the benefit that thread creation and destruction overhead is restricted to the initial creation of the pool, which may result in better performance.
The implementation is dependency and unsafe-free.
use base_threadpool::{ThreadPool, ThreadPoolBuilder};
use std::sync::{Arc, Mutex};
let thread_pool = ThreadPoolBuilder::default().build();
let value = Arc::new(Mutex::new(0));
(0..4).for_each(move |_| {
let value = Arc::clone(&value);
thread_pool.execute(move || {
let mut ir = 0;
(0..100_000_000).for_each(|_| {
ir += 1;
});
let mut lock = value.lock().unwrap();
*lock += ir;
});
});You can create a ThreadPool using the builder pattern:
use base_threadpool::ThreadPool;
// create a thread pool with default settings
let pool = ThreadPool::builder().build();
// create a customized thread pool
let custom_pool = ThreadPool::builder()
.num_threads(4)
.stack_size(3 * 1024 * 1024)
.name_prefix("worker".to_string())
.build();Use the execute method to submit tasks to the thread pool:
pool.execute(|| {
// Your task here
println!("Task executed by thread pool");
});To wait for all tasks to complete:
pool.join();MIT
