+Processing of `data:` URLs in Rust according to the Fetch Standard:
+<https://fetch.spec.whatwg.org/#data-urls>
+but starting from a string rather than a parsed URL to avoid extra copies.
+
+```rust
+use data_url::{DataUrl, mime};
+//!
+let url = DataUrl::process("data:,Hello%20World!").unwrap();
+let (body, fragment) = url.decode_to_vec().unwrap();
+//!
+assert_eq!(url.mime_type().type_, "text");
+assert_eq!(url.mime_type().subtype, "plain");
+assert_eq!(url.mime_type().get_parameter("charset"), Some("US-ASCII"));
+assert_eq!(body, b"Hello World!");
+assert!(fragment.is_none());
+```
