Function faketime::faketime::millis_tempfile

pub fn millis_tempfile(millis: u64) -> Result<TempPath>

Writes time into a temporary file and return the file.

It returns the handle to the timestamp file on success.

use std::fs;

let faketime_file = faketime::millis_tempfile(123).expect("create faketime file");
assert_eq!(fs::read_to_string(&faketime_file).ok(), Some("123".to_string()));

The file is deleted when the handle goes out of scope.

let path = {
    let faketime_file = faketime::millis_tempfile(123).expect("create faketime file");
    faketime_file.to_path_buf()
};
assert!(!path.exists());
