Enum hyperx::header::Vary

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

• accept-encoding, accept-language

Example

use hyperx::header::{TypedHeaders, Vary};

let mut headers = http::HeaderMap::new();
headers.encode(&Vary::Any);

Example

// extern crate unicase;

use hyperx::header::{TypedHeaders, Vary};
use unicase::Ascii;

let mut headers = http::HeaderMap::new();
headers.encode(
    &Vary::Items(vec![
        Ascii::new("accept-encoding".to_owned()),
        Ascii::new("accept-language".to_owned()),
    ])
);

Variants

Any

Any value is a match

Items(Vec<Ascii<String>>)

Only the listed items are a match

Tuple Fields of Items

0: Vec<Ascii<String>>
