format a date in to the format 'yyyy-mm-dd hh:mm:ss' in rust

To format a date in the format yyyy-mm-dd hh:mm:ss, we can use the format method provided by the chrono crate. Here's an example code snippet that demonstrates this:

main.rs
use chrono::{DateTime, Utc, TimeZone};

fn main() {
    let dt: DateTime<Utc> = Utc::now();
    let formatted_date = dt.format("%Y-%m-%d %H:%M:%S").to_string();
    println!("{}", formatted_date);
}
199 chars
8 lines

Explanation:

1. We import the required modules from chrono crate.

2. We get the current date and time in the UTC timezone using the Utc::now() method.

3. We use the format() method provided by DateTime to get the formatted date string. The %Y-%m-%d %H:%M:%S is the format string, where %Y represents the year, %m represents the month, %d represents the day, %H represents the hour, %M represents the minute, and %S represents the second.

4. Finally, we call the to_string() method to create a String representation of the formatted date.

5. We add the String tag since we are converting the formatted date to a string.
