Support MIME (Media Types) as strong types in Rust.
extern crate mime; // common types are constants let text = mime::TEXT_PLAIN; // deconstruct Mimes to match on them match (text.type_(), text.subtype()) { (mime::TEXT, mime::PLAIN) => { // plain text! }, (mime::TEXT, _) => { // structured text! }, _ => { // not text! } }
