pub struct Vary(/* private fields */);
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();
