Implementations§

Source§

impl ThreadUtil

Source

pub fn new(thread_num: usize) -> Self

创建一个线程池,并执行任务

§参数
  • thread_num - 线程池中的线程数量
Source

pub fn execute<F>(&self, task: F)
where F: FnOnce() + Send + 'static,

执行一个任务函数

该函数将给定的任务提交到线程池中执行。任务必须是只执行一次的闭包, 并且需要满足线程安全和生命周期要求。

§参数
  • task - 要执行的任务函数,必须实现FnOnce、Send和’static约束
§泛型参数
  • F - 任务函数的类型,必须满足FnOnce() + Send + ’static约束
Source

pub fn join(&self)

等待线程池中的所有任务执行完成

此函数会阻塞当前线程,直到线程池中的所有任务都执行完毕。 调用此函数后,线程池将不再接受新的任务。

Source

pub fn spawn<F, T>(f: F) -> JoinHandle<T>
where F: FnOnce() -> T + Send + 'static, T: Send + 'static,
