relativetime

relativetime 为 std::time::Duration 和 chrono::Duration 提供了 trait，以便轻松显示可读的相对时间。

use relativetime::{RelativeTime, NegativeRelativeTime};


fn main() {
    let d = std::time::Duration::from_secs(1);
    assert_eq!(d.relative_time(), "in a few seconds");
    assert_eq!(d.relative_time_in_past(), "a few seconds ago");
    
    let d = chrono::Duration::from_secs(-1);
    assert_eq!(d.relative_time(), "a few seconds ago");
    let d = chrono::Duration::from_secs(1);
    assert_eq!(d.relative_time(), "in a few seconds");
}
