[−][src]Struct threaded::ThreadPool
Thread pool of workers awaiting execution orders.
Implementations
impl ThreadPool
[src]
pub fn new(capacity: usize) -> ThreadPool
[src]
Create a new ThreadPool.
The capacity is the number of desired threads in the pool.
Panics
The new
function will panic if the capacity is zero.
Examples
use std::sync::Arc; use std::sync::atomic::{ Ordering, AtomicBool }; use threaded::ThreadPool; let num_workers = 2; let tp = ThreadPool::new(num_workers); assert_eq!(tp.capacity(), num_workers); let has_executed = Arc::new(AtomicBool::new(false)); { let has_executed = has_executed.clone(); tp.execute(move || { has_executed.swap(true, Ordering::SeqCst); }); } drop(tp); // block main thread until execute finishes (uses handle.join()) assert_eq!(has_executed.load(Ordering::SeqCst), true);
pub fn capacity(&self) -> usize
[src]
Capacity of thread pool (number of workers).
pub fn resize(&mut self, capacity: usize)
[src]
Resize thread pool to new capacity
Panics
The resize
function will panic if the capacity is zero.
Caution: Dead workers aren't removed from pool wasting memory but is fault tolerant.
pub fn execute<F>(&self, f: F) where
F: FnOnce() + Send + 'static,
[src]
F: FnOnce() + Send + 'static,
Execute function/closure using worker from thread pool.
