Parse RSS pub_date with std

help
1

I want something like that:

use chrono::{Datelike, NaiveDateTime, Timelike};
use std::{fs::create_dir_all, path::MAIN_SEPARATOR};

let date_time = NaiveDateTime::parse_from_str(pub_date, "%a, %d %b %Y %H:%M:%S %Z")?;

let dir = format!(
    "{base}{MAIN_SEPARATOR}{:02}{MAIN_SEPARATOR}{:02}{MAIN_SEPARATOR}{:02}",
    date_time.year(),
    date_time.month(),
    date_time.day()
);

Do I really want the chrono crate here?
And this construction "%a, %d %b %Y %H:%M:%S %Z" just to parse RFC 2822 into the object

I think that wrote some kind of trash code :slight_smile:

Chrono has a dedicated routine for parsing RFC 2822: DateTime in chrono - Rust

As does Jiff: parse in jiff::fmt::rfc2822 - Rust

I don't know what you're trying to do, but yeah, you probably want a datetime crate for this. It also depends on what you want to do with the result, which is unclear from your post here.

Thank you, now it's much better!

let date_time = DateTime::parse_from_rfc2822(pub_date)?;

ps. I'm trying to extract y/m/d as the filename members for the feed cache
