Format std :: time output

Question

I want to display the current time in a specific format.

I am trying to avoid time crate as it is marked as deprecated on the GitHub repository .

I want to use this exact format time::now().strftime("%Y-%m-%d][%H:%M:%S").unwrap()with help std::time, but it doesn’t strftime.

Answer 1

There are (currently) two methods now: Instant::nowand SystemTime::now.

Instant He speaks:

Measurement of monotonically increasing hours. Opaque and useful only with Duration.

SystemTime He speaks:

Measuring system clocks useful for communicating with external objects, such as a file system or other processes.

Answer 2

chrono :

extern crate chrono;

use chrono::Local;

fn main() {
    let date = Local::now();
    println!("{}", date.format("%Y-%m-%d][%H:%M:%S"));
}
