pub struct Poller { /* fields omitted */ }

定义文件 I/O 事件通知器。

Methods

impl Poller[src]

pub fn new() -> Self[src]

创建一个新的 I/O 事件通知器。

pub fn add(&mut self, fd: i32, events: Events) -> Result<(), SysError>[src]

添加一个文件描述符到监视列表中。

pub fn remove(&mut self, fd: i32) -> Result<(), SysError>[src]

将一个文件描述符从监视列表中移除。

pub fn pull_events(
    &self,
    timeout_ms: i32
) -> Result<Vec<(i32, Events)>, SysError>[src]

拉取所有被监测到的 I/O 事件。

Examples

let mut poller = Poller::new();
poller.add(0, Events::new().with_read());

    println!("Fd={}, Events={}", fd, events);
}
