Preview-rs

A rust crate to fetch preview metadata for a URL.

Things left to be done:

• [ ] More fallback options especially for images.
• [ ] Support more multimedia options than images (video, png, etc).
• [ ] Allow passing custom user-agent in the request.

Usage

```rust let prev = previewrs::Preview::new("https://deezer.com"); let preview = prev.fetchpreview(); println!("Here is the preview of this URL: {:?}", &preview);

/** PreviewResponse {
   description: Some("You bring the passion, we bring the music! Access more than 73 million tracks, anytime, anywhere!"),
   title: Some("Deezer | Listen to music | Online music streaming platform"),
   url: Some("http://www.deezer.com"),
   name: Some("Deezer"),
   image: Some("https://e-cdns-files.dzcdn.net/img/common/opengraph-logo.png")
 }
