threadpool_scope

为 threadpools 添加作用域的库。本质上类似于 scoped_threadpool，但针对 threadpool 进行了适配。

更多详情，请参阅 文档。

注意：threadpool crate 预计将在下一个主要版本（2.0）中获得作用域功能，这将消除对当前库的需求。

入门指南

threadpool_scope 在 crates.io 上可用。将以下依赖项添加到您的 Cargo 清单中，以获取 0.1 分支的最新版本

[dependencies]
threadpool_scope = "0.1.*"

示例

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]);
}
