Struct Interest 

pub struct Interest {
    pub readable: bool,
    pub writable: bool,
    pub priority: bool,
    pub oneshot: bool,
    pub edge: bool,
}

Interest types for file descriptor registration 文件描述符注册的兴趣类型

Specifies which events the driver should monitor for a file descriptor. 指定driver应监控文件描述符的哪些事件。

Fields

readable: bool

Monitor for readability / 监控可读性

writable: bool

Monitor for writability / 监控可写性

priority: bool

Priority hint for edge-triggered mode / 边缘触发模式的优先级提示

oneshot: bool

One-shot mode: auto-deregister after one event / 单次模式：事件后自动取消注册

edge: bool

Edge-triggered mode vs level-triggered / 边缘触发模式 vs 水平触发

Trait Implementations

impl Clone for Interest

fn clone(&self) -> Interest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Interest

impl Debug for Interest

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

Formats the value using the given formatter.

impl Default for Interest

fn default() -> Interest

Returns the “default value” for a type.

impl Eq for Interest

impl PartialEq for Interest

fn eq(&self, other: &Interest) -> 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.
