Enum EpollCtl

#[repr(u8)]
pub enum EpollCtl {
    ADD = 1,
    DEL = 2,
    MOD = 3,
}

epoll_ctl 操作类型，用于管理 epoll 实例中的监听目标（fd）。

Variants

ADD = 1

添加一个新的监听目标到 epoll 实例中（epoll_ctl(epfd, EPOLL_CTL_ADD, fd, event)）

DEL = 2

从 epoll 实例中删除一个监听目标（epoll_ctl(epfd, EPOLL_CTL_DEL, fd, NULL)）

MOD = 3

修改已添加目标的监听事件（epoll_ctl(epfd, EPOLL_CTL_MOD, fd, event)）

Trait Implementations

impl Debug for EpollCtl

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EpollCtl

fn eq(&self, other: &EpollCtl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u8> for EpollCtl

type Error = TryFromPrimitiveError<EpollCtl>

The type returned in the event of a conversion error.

fn try_from(number: u8) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for EpollCtl

const NAME: &'static str = "EpollCtl"

type Primitive = u8

type Error = TryFromPrimitiveError<EpollCtl>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>
