Struct Itimerval 

Source 
#[repr(C)]
pub struct Itimerval {
    pub it_interval: timeval,
    pub it_value: timeval,
}
Expand description

用于设置传统 BSD 间隔定时器 (setitimer) 的结构。

Fields§

§it_interval: timeval

定时器周期 (timer interval)

§it_value: timeval

定时器当前值 (current value)

Implementations§

Source§

impl Itimerval

Source

pub fn zero() -> Self

impl PartialEq for Itimerval

Source§

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