A library for adding scopes to threadpools. Essentially scoped_threadpool, but adapted for use with threadpool.
For more details, see the docs.
Note: the threadpool crate is expected to gain scope functionality in the next major version (2.0), which should obviate the need for this crate.
threadpool_scope is available on crates.io. Add the following dependency to your Cargo manifest to get the latest version of the 0.1 branch:
[dependencies]
threadpool_scope = "0.1.*"
use threadpool::ThreadPool;
use threadpool_scope::scope_with;
fn main() {
// Create a threadpool holding 4 threads
let mut pool = ThreadPool::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
scope_with(&pool, |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]);
}
