Struct Vary

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

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

pub fn any() -> Vary

Create a new Very: * header.

pub fn is_any(&self) -> bool

Check if this includes *.

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

Iterate the header names of this Vary.

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<(), Error>

Formats the value using the given formatter.

impl Header for Vary

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I>(values: &mut I) -> Result<Vary, Error>

where I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

fn encode<E>(&self, values: &mut E)

where E: Extend<HeaderValue>,

Encode this type to a HeaderMap.

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.
