Crate scoped_threadpool [−] [src]
This crate provides a stable, safe and scoped threadpool.
It can be used to execute a number of short-lived jobs in parallel without the need to respawn the underlying threads.
Jobs are runnable by borrowing the pool for a given scope, during which
an arbitrary number of them can be executed. These jobs can access data of
any lifetime outside of the pools scope, which allows working on
non-'static
references in parallel.
For safety reasons, a panic inside a worker thread will not be isolated, but rather propagate to the outside of the pool.
Examples:
extern crate scoped_threadpool; use scoped_threadpool::Pool; fn main() { // Create a threadpool holding 4 threads let mut pool = Pool::new(4); let mut vec = vec![0, 1, 2, 3, 4, 5, 6, 7]; // Use the threads as scoped threads that can // reference anything outside this closure pool.scoped(|scope| { // Create references to each element in the vector ... for e in &mut vec { // ... and add 1 to it in a seperate thread scope.execute(move || { *e += 1; }); } }); assert_eq!(vec, vec![1, 2, 3, 4, 5, 6, 7, 8]); }
