Question

How to create a vector of days starting with today and going back the last 30 days in Rust

Answer 1

use chrono::{Local, Datelike};

fn main() {
    // Get today's date
    let today = Local::now().date_naive();

    // Create a vector to store the days
    let mut days = Vec::new();

    // Populate the vector with the last 30 days
    for i in 0..30 {
        let past_date = today - chrono::Duration::days(i);
        days.push(past_date.day());
    }

    for day in &days {
        println!("{}", day);
    }
}
