Struct headers::Vary

source ·
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();

impl PartialEq for Vary

source§

fn eq(&self, other: &Vary) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
