This crate provides two MediaType structs: MediaType and MediaTypeBuf.

• MediaType does not copy data during parsing and just holds reference to the original string. It is also const-constructible.
• MediaTypeBuf is an owned and immutable version of MediaType.

```rust use mediatype::{names::*, MediaType, MediaTypeBuf};

const TEXTPLAIN: MediaType = MediaType::new(TEXT, PLAIN); let textplain: MediaTypeBuf = "text/plain".parse().unwrap();

asserteq!(textplain, TEXT_PLAIN);

match (textplain.ty(), textplain.subty()) { ("text", "plain") => println!("plain text!"), ("text", _) => println!("structured text"), _ => println!("not text"), } ```
