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