Struct timeval 

#[repr(C)]
pub struct timeval {
    pub tv_sec: c_long,
    pub tv_usec: c_long,
}

用于指定秒和微秒精度的时间。

Fields

tv_sec: c_long

秒 (seconds)

tv_usec: c_long

微秒 (microseconds)

Implementations

impl timeval

pub fn to_timespec(&self) -> TimeSpec

将 timeval 转换为 TimeSpec 结构体。

返回值:

• 对应的 TimeSpec 结构体

pub fn into_freq(&self, freq: usize) -> usize

将 timeval 转换为指定频率的刻度数。

参数:

• freq: 频率（每秒刻度数）

返回值:

• 刻度数

pub fn new(sec: c_long, usec: c_long) -> Self

创建一个新的 timeval 结构体

参数:

• sec: 秒数
• usec: 微秒数

返回值:

• 对应的 timeval 结构体

pub fn zero() -> Self

创建零时间的 timeval 结构体

返回值:

• 零时间的 timeval 结构体

pub fn is_zero(&self) -> bool

检查是否为零时间

Trait Implementations

impl Clone for timeval

fn clone(&self) -> timeval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for timeval

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

Formats the value using the given formatter.

impl PartialEq for timeval

fn eq(&self, other: &timeval) -> 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 Copy for timeval

impl Eq for timeval
