pub struct Vary(_);

[−] 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 headers::Vary;

let vary = Vary::any();

Create a new Very: * header.

pub fn is_any(&self) -> bool[−]

Check if this includes *.

pub fn iter_strs(&self) -> impl Iterator<Item = &str>[−]
