This module has a ensure_downloaded function which takes a slice of Urls. It downloads all of the urls to a local downloads folder (if they aren't already downloaded) and returns.

use std::fs::rename, DirBuilder, File;

use url::Url;

/// Return the local path where the given url will be stored.
pub fn downloaded_path(url: &Url) -> PathBuf 
 PathBuf::from("downloads")
 .join(url.host_str().unwrap())
 .join(&url.path()[1..])


/// Ensure that all the urls are downloaded into a local downloads directory.

          Function to Return a JSON Like Objects Using VBA Collections and Arrays

          Image
          Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with.
