Struct salvo::http::headers::Vary[][src]

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();

Implementations

impl Vary[src]
