[−][src]Crate slave_pool
Simple thread pool
Example
use slave_pool::ThreadPool; const SECOND: core::time::Duration = core::time::Duration::from_secs(1); static POOL: ThreadPool = ThreadPool::new(); POOL.set_threads(8); //Tell how many threads you want let mut handles = Vec::new(); for _ in 0..8 { handles.push(POOL.spawn_handle(|| { std::thread::sleep(SECOND); })); } POOL.set_threads(0); //Tells to shut down threads for handle in handles { assert!(handle.wait().is_ok()) //Even though we told it to shutdown all threads, it is going to finish queued job first } let handle = POOL.spawn_handle(|| {}); assert!(handle.wait_timeout(SECOND).is_err()); // All are shutdown now POOL.set_threads(1); //But let's add one more assert!(handle.wait().is_ok()); let handle = POOL.spawn_handle(|| panic!("Oh no!")); // We can panic, if we want assert!(handle.wait().is_err()); // In that case we'll get error, but thread will be ok let handle = POOL.spawn_handle(|| {}); POOL.set_threads(0); assert!(handle.wait().is_ok());
