Expand description

Vary header, defined in RFC7231

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

Vary = "*" / 1#field-name

Example values

  • accept-encoding, accept-language

Example

use hyper::header::{Headers, Vary};

let mut headers = Headers::new();
headers.set(Vary::Any);

Example

// extern crate unicase;

use hyper::header::{Headers, Vary};
use unicase::UniCase;

let mut headers = Headers::new();
headers.set(
    Vary::Items(vec![
        UniCase("accept-encoding".to_owned()),
        UniCase("accept-language".to_owned()),
    ])
);

Variants

Any

Any value is a match

Items(Vec<UniCase<String>, Global>)

Only the listed items are a match
