| //! |
| //! Mime is now Media Type, technically, but `Mime` is more immediately |
| //! understandable, so the main type here is `Mime`. |
| //! |
| //! ## What is Mime? |
| //! |
| //! Example mime string: `text/plain` |
| //! |
| //! ``` |
| //! let plain_text: mime::Mime = "text/plain".parse().unwrap(); |
| //! assert_eq!(plain_text, mime::TEXT_PLAIN); |
| //! ``` |
| //! |
| //! ## Inspecting Mimes |
| //! |
| //! ``` |
| //! let mime = mime::TEXT_PLAIN; |
| //! match (mime.type_(), mime.subtype()) { |
| //! (mime::TEXT, mime::PLAIN) => println!("plain text!"), |
| //! (mime::TEXT, _) => println!("structured text"), |
| //! _ => println!("not text"), |
| //! } |
| //! ``` |
