I'm trying to parse a std::time::Instant into a String, but I don't know how to do it properly.
use std::{time::Instant};
// let my_str: String = Instant::now();
The Instant struct doesn't seem to have a parse or to_string method.
I want to get the current timestamp, could be in any format, and store it in a struct/database as a String.
As the documentation of std::time::Instant mentions:
Instants are opaque types that can only be compared to one another.
For a more complete time library, which supports time zones and printing, use chrono, whose documentation has a whole section about formatting time.
If you want to store the time in a database, then you are most likely interested in the to_rfc3339 method which serializes time as per ISO 8601/RFC3339:
use chrono::Utc;
fn main() {
let time = Utc::now();
println!("{}", time.to_rfc3339());
}
prints 2022-02-26T16:17:33.088851150+00:00.
