Struct std::fs::FileTimes

文件上各种时间戳的表示

1.Implementations

impl FileTimes

new()

创建一个没有设置时间的新 FileTimes。

pub fn new() -> Self

返回值：返回一个新的FileTimes

use std::fs::FileTimes;

fn main() {
    let t = FileTimes::new();
    println!("{:#?}", t);

	/*
		FileTimes(
			FileTimes {
				accessed: None,
				modified: None,
				created: None,
			},
		)
	 */
}

set_accessed()

设置文件的最后访问时间。

pub fn set_accessed(self, t: SystemTime) -> Self

参数：

• t：系统时钟的度量SystemTime

返回值：返回自身

use std::fs::FileTimes;
use std::time::SystemTime;
fn main() {
    let t = FileTimes::new();
	t.set_accessed(SystemTime::now());
    println!("{:#?}", t);
}

set_modified()

设置文件的最后修改时间。

pub fn set_accessed(self, t: SystemTime) -> Self

参数：

• t：系统时钟的度量SystemTime

返回值：返回自身
