Enum Vary

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

Trait Implementations

impl Clone for Vary

fn clone(&self) -> Vary

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Vary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Header for Vary

fn header_name() -> &'static str

Returns the name of the header field this belongs to.

fn parse_header(raw: &Raw) -> Result<Self>

Parse a header from a raw stream of bytes.

fn fmt_header(&self, f: &mut Formatter<'_, '_>) -> Result

Format a header to outgoing stream.

impl PartialEq for Vary

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

Tests for self and other values to be equal, and is used by ==.

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

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