Enum hyper::header::Vary [] [src]

pub enum Vary {
    Any,
    Items(Vec<Ascii<String>>),
}

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

Example

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