Struct Cookie 

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

Cookie header, defined in RFC6265

If the user agent does attach a Cookie header field to an HTTP request, the user agent must send the cookie-string as the value of the header field.

When the user agent generates an HTTP request, the user agent MUST NOT attach more than one Cookie header field.

Example values

• SID=31d4d96e407aad42
• SID=31d4d96e407aad42; lang=en-US

Implementations

impl Cookie

pub fn get(&self, name: &str) -> Option<&str>

Lookup a value for a cookie name.

Example

use headers::{Cookie, HeaderMap, HeaderMapExt, HeaderValue};

// Setup the header map with strings...
let mut headers = HeaderMap::new();
headers.insert("cookie", HeaderValue::from_static("lang=en-US"));

// Parse a `Cookie` so we can play with it...
let cookie = headers
    .typed_get::<Cookie>()
    .expect("we just inserted a valid Cookie");

assert_eq!(cookie.get("lang"), Some("en-US"));
assert_eq!(cookie.get("SID"), None);

pub fn len(&self) -> usize

Get the number of key-value pairs this Cookie contains.

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

Iterator the key-value pairs of this Cookie header.

Trait Implementations

impl Clone for Cookie

fn clone(&self) -> Cookie

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cookie

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

Formats the value using the given formatter.

impl Header for Cookie

fn name() -> &'static HeaderName

The name of this header.

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

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

Decode this type from an iterator of HeaderValues.

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

Encode this type to a HeaderMap.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
