//! # Mime
|
||||
//!
|
||||
//! 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"),
|
||||
//! }
|
||||
//! ```
