+/// `Vary` header, defined in [RFC7231](https://tools.ietf.org/html/rfc7231#section-7.1.4)
+///
+/// The "Vary" header field in a response describes what parts of a
+/// request message, aside from the method, Host header field, and
+/// request target, might influence the origin server's process for
+/// selecting and representing this response.  The value consists of
+/// either a single asterisk ("*") or a list of header field names
+/// (case-insensitive).
+///
+/// # ABNF
+///
+/// ```text
+/// Vary = "*" / 1#field-name
+/// ```
+///
+/// # Example values
+///
+/// * `accept-encoding, accept-language`
+///
+/// # Example
+///
+/// ```
+/// # extern crate headers;
+/// use headers::Vary;
+///
+/// let vary = Vary::any();
+/// ```
