Struct rocket::http::Cookie

pub struct Cookie<'c> { /* fields omitted */ }

Representation of an HTTP cookie.

Constructing a Cookie

To construct a cookie with only a name/value, use the new method:

use cookie::Cookie;

let cookie = Cookie::new("name", "value");
assert_eq!(&cookie.to_string(), "name=value");

To construct more elaborate cookies, use the build method and CookieBuilder methods:

use cookie::Cookie;

let cookie = Cookie::build("name", "value")
    .domain("www.rust-lang.org")
    .path("/")
    .secure(true)
    .http_only(true)
    .finish();

Methods

impl Cookie<'static>

fn new<N, V>(name: N, value: V) -> Cookie<'static> where
    N: Into<Cow<'static, str>>,
    V: Into<Cow<'static, str>>, 

Creates a new Cookie with the given name and value.

Example

use cookie::Cookie;

let cookie = Cookie::new("name", "value");
assert_eq!(cookie.name_value(), ("name", "value"));

fn build<N, V>(name: N, value: V) -> CookieBuilder where
    N: Into<Cow<'static, str>>,
    V: Into<Cow<'static, str>>, 

Creates a new CookieBuilder instance from the given key and value strings.

Example

use cookie::Cookie;

let c = Cookie::build("foo", "bar").finish();
assert_eq!(c.name_value(), ("foo", "bar"));

impl<'c> Cookie<'c>

fn parse<S>(s: S) -> Result<Cookie<'c>, ParseError> where
    S: Into<Cow<'c, str>>, 

Parses a Cookie from the given HTTP cookie header value string. Does not perform any percent-decoding.

Example

use cookie::Cookie;

let c = Cookie::parse("foo=bar%20baz; HttpOnly").unwrap();
assert_eq!(c.name_value(), ("foo", "bar%20baz"));
assert_eq!(c.http_only(), true);

fn parse_encoded<S>(s: S) -> Result<Cookie<'c>, ParseError> where
    S: Into<Cow<'c, str>>, 

Parses a Cookie from the given HTTP cookie header value string where the name and value fields are percent-encoded. Percent-decodes the name/value fields.

This API requires the percent-encode feature to be enabled on this crate.

Example

use cookie::Cookie;

let c = Cookie::parse_encoded("foo=bar%20baz; HttpOnly").unwrap();
assert_eq!(c.name_value(), ("foo", "bar baz"));
assert_eq!(c.http_only(), true);

fn encoded(&'a self) -> EncodedCookie<'a, 'c>

Wraps self in an EncodedCookie: a cost-free wrapper around Cookie whose Display implementation percent-encodes the name and value of the wrapped Cookie.

This method is only available when the percent-encode feature is enabled.

Example

use cookie::Cookie;

let mut c = Cookie::new("my name", "this; value?");
assert_eq!(&c.encoded().to_string(), "my%20name=this%3B%20value%3F");

fn into_owned(self) -> Cookie<'static>

Converts self into a Cookie with a static lifetime. This method results in at most one allocation.

Example

use cookie::Cookie;

let c = Cookie::new("a", "b");
let owned_cookie = c.into_owned();
assert_eq!(owned_cookie.name_value(), ("a", "b"));

fn name(&self) -> &str

Returns the name of self.

Example

use cookie::Cookie;

let c = Cookie::new("name", "value");
assert_eq!(c.name(), "name");

fn value(&self) -> &str

Returns the value of self.

Example

use cookie::Cookie;

let c = Cookie::new("name", "value");
assert_eq!(c.value(), "value");

fn name_value(&self) -> (&str, &str)

Returns the name and value of self as a tuple of (name, value).

Example

use cookie::Cookie;

let c = Cookie::new("name", "value");
assert_eq!(c.name_value(), ("name", "value"));

fn http_only(&self) -> bool

Returns whether this cookie was marked HttpOnly or not.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value; httponly").unwrap();
assert_eq!(c.http_only(), true);

fn secure(&self) -> bool

Returns whether this cookie was marked Secure or not.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value; Secure").unwrap();
assert_eq!(c.secure(), true);

fn max_age(&self) -> Option<Duration>

Returns the specified max-age of the cookie if one was specified.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value").unwrap();
assert_eq!(c.max_age(), None);

let c = Cookie::parse("name=value; Max-Age=3600").unwrap();
assert_eq!(c.max_age().map(|age| age.num_hours()), Some(1));

fn path(&self) -> Option<&str>

Returns the Path of the cookie if one was specified.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value").unwrap();
assert_eq!(c.path(), None);

let c = Cookie::parse("name=value; Path=/").unwrap();
assert_eq!(c.path(), Some("/"));

let c = Cookie::parse("name=value; path=/sub").unwrap();
assert_eq!(c.path(), Some("/sub"));

fn domain(&self) -> Option<&str>

Returns the Domain of the cookie if one was specified.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value").unwrap();
assert_eq!(c.domain(), None);

let c = Cookie::parse("name=value; Domain=crates.io").unwrap();
assert_eq!(c.domain(), Some("crates.io"));

fn expires(&self) -> Option<Tm>

Returns the Expires time of the cookie if one was specified.

Example

use cookie::Cookie;

let c = Cookie::parse("name=value").unwrap();
assert_eq!(c.expires(), None);

let expire_time = "Wed, 21 Oct 2017 07:28:00 GMT";
let cookie_str = format!("name=value; Expires={}", expire_time);
let c = Cookie::parse(cookie_str).unwrap();
assert_eq!(c.expires().map(|t| t.tm_year), Some(117));

fn set_name<N>(&mut self, name: N) where
    N: Into<Cow<'static, str>>, 

Sets the name of self to name.

Example

use cookie::Cookie;

let mut c = Cookie::new("name", "value");
assert_eq!(c.name(), "name");

c.set_name("foo");
