Struct Cookie

pub struct Cookie<'a> {
    pub path: CookiePath,
    pub domain: CookieDomain,
    pub expires: CookieExpiration,
    /* private fields */
}

A cookie conforming more closely to IETF RFC6265

Fields

path: CookiePath

The Path attribute from a Set-Cookie header or the default-path as determined from the request-uri

domain: CookieDomain

The Domain attribute from a Set-Cookie header, or a HostOnly variant if no non-empty Domain attribute found

expires: CookieExpiration

For a persistent Cookie (see IETF RFC6265 Section 5.3), the expiration time as defined by the Max-Age or Expires attribute, otherwise SessionEnd, indicating a non-persistent Cookie that should expire at the end of the session

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

Methods from Deref<Target = RawCookie<'a>>

pub fn name(&self) -> &str

Returns the name of self.

Example

use cookie::Cookie;

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

pub fn value(&self) -> &str

Returns the value of self.

Example

use cookie::Cookie;

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

pub 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"));

pub fn http_only(&self) -> Option<bool>

Returns whether this cookie was marked HttpOnly or not. Returns Some(true) when the cookie was explicitly set (manually or parsed) as HttpOnly, Some(false) when http_only was manually set to false, and None otherwise.

Example

use cookie::Cookie;

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

let mut c = Cookie::new("name", "value");
assert_eq!(c.http_only(), None);

let mut c = Cookie::new("name", "value");
assert_eq!(c.http_only(), None);

// An explicitly set "false" value.
c.set_http_only(false);
assert_eq!(c.http_only(), Some(false));

// An explicitly set "true" value.
c.set_http_only(true);
assert_eq!(c.http_only(), Some(true));

pub fn secure(&self) -> Option<bool>

Returns whether this cookie was marked Secure or not. Returns Some(true) when the cookie was explicitly set (manually or parsed) as Secure, Some(false) when secure was manually set to false, and None otherwise.

Example

use cookie::Cookie;

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

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

let mut c = Cookie::new("name", "value");
assert_eq!(c.secure(), None);

// An explicitly set "false" value.
c.set_secure(false);
assert_eq!(c.secure(), Some(false));

// An explicitly set "true" value.
c.set_secure(true);
assert_eq!(c.secure(), Some(true));

pub fn same_site(&self) -> Option<SameSite>

Returns the SameSite attribute of this cookie if one was specified.

Example

use cookie::{Cookie, SameSite};

let c = Cookie::parse("name=value; SameSite=Lax").unwrap();
assert_eq!(c.same_site(), Some(SameSite::Lax));

pub 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.whole_hours()), Some(1));

pub 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"));

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

Returns the Domain of the cookie if one was specified.

This does not consider whether the Domain is valid; validation is left to higher-level libraries, as needed. However, if the Domain starts with a leading ., the leading . is stripped.

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"));

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

// Note that `..crates.io` is not a valid domain.
let c = Cookie::parse("name=value; Domain=..crates.io").unwrap();
assert_eq!(c.domain(), Some(".crates.io"));

pub fn expires(&self) -> Option<Expiration>

Returns the Expiration of the cookie if one was specified.

Example

use cookie::{Cookie, Expiration};

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

// Here, `cookie.expires_datetime()` returns `None`.
let c = Cookie::build("name", "value").expires(None).finish();
assert_eq!(c.expires(), Some(Expiration::Session));

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().and_then(|e| e.datetime()).map(|t| t.year()), Some(2017));

pub fn expires_datetime(&self) -> Option<OffsetDateTime>

Returns the expiration date-time of the cookie if one was specified.

Example

use cookie::Cookie;

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

// Here, `cookie.expires()` returns `Some`.
let c = Cookie::build("name", "value").expires(None).finish();
assert_eq!(c.expires_datetime(), 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_datetime().map(|t| t.year()), Some(2017));

pub fn name_raw(&self) -> Option<&'c str>

Returns the name of self as a string slice of the raw string self was originally parsed from. If self was not originally parsed from a raw string, returns None.

This method differs from Cookie::name() in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive self. If a longer lifetime is not required, or you’re unsure if you need a longer lifetime, use Cookie::name().

Example

use cookie::Cookie;

let cookie_string = format!("{}={}", "foo", "bar");

// `c` will be dropped at the end of the scope, but `name` will live on
let name = {
    let c = Cookie::parse(cookie_string.as_str()).unwrap();
    c.name_raw()
};

assert_eq!(name, Some("foo"));

pub fn value_raw(&self) -> Option<&'c str>

Returns the value of self as a string slice of the raw string self was originally parsed from. If self was not originally parsed from a raw string, returns None.

This method differs from Cookie::value() in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive self. If a longer lifetime is not required, or you’re unsure if you need a longer lifetime, use Cookie::value().

Example

use cookie::Cookie;

let cookie_string = format!("{}={}", "foo", "bar");

// `c` will be dropped at the end of the scope, but `value` will live on
let value = {
    let c = Cookie::parse(cookie_string.as_str()).unwrap();
    c.value_raw()
};

assert_eq!(value, Some("bar"));

pub fn path_raw(&self) -> Option<&'c str>

Returns the Path of self as a string slice of the raw string self was originally parsed from. If self was not originally parsed from a raw string, or if self doesn’t contain a Path, or if the Path has changed since parsing, returns None.

This method differs from Cookie::path() in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive self. If a longer lifetime is not required, or you’re unsure if you need a longer lifetime, use Cookie::path().

Example

use cookie::Cookie;

let cookie_string = format!("{}={}; Path=/", "foo", "bar");

// `c` will be dropped at the end of the scope, but `path` will live on
let path = {
    let c = Cookie::parse(cookie_string.as_str()).unwrap();
    c.path_raw()
};

assert_eq!(path, Some("/"));

pub fn domain_raw(&self) -> Option<&'c str>

Returns the Domain of self as a string slice of the raw string self was originally parsed from. If self was not originally parsed from a raw string, or if self doesn’t contain a Domain, or if the Domain has changed since parsing, returns None.

Like Cookie::domain(), this does not consider whether Domain is valid; validation is left to higher-level libraries, as needed. However, if Domain starts with a leading ., the leading . is stripped.

This method differs from Cookie::domain() in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive self struct. If a longer lifetime is not required, or you’re unsure if you need a longer lifetime, use Cookie::domain().

Example

use cookie::Cookie;

let cookie_string = format!("{}={}; Domain=.crates.io", "foo", "bar");

//`c` will be dropped at the end of the scope, but `domain` will live on
let domain = {
    let c = Cookie::parse(cookie_string.as_str()).unwrap();
    c.domain_raw()
};

assert_eq!(domain, Some("crates.io"));

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

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

The returned structure can be chained with Display::stripped() to display only the name and value.

Example

use cookie::Cookie;

let mut c = Cookie::build("my name", "this; value?").secure(true).finish();
assert_eq!(&c.encoded().to_string(), "my%20name=this%3B%20value%3F; Secure");
assert_eq!(&c.encoded().stripped().to_string(), "my%20name=this%3B%20value%3F");

pub fn stripped<'a>(&'a self) -> Display<'a, 'c>

Wraps self in a stripped Display]: a cost-free wrapper around Cookie whose fmt::Display implementation prints only the name and value of the wrapped Cookie.

The returned structure can be chained with Display::encoded() to encode the name and value.

Example

use cookie::Cookie;

let mut c = Cookie::build("key?", "value").secure(true).path("/").finish();
assert_eq!(&c.stripped().to_string(), "key?=value");
// Note: `encoded()` is only available when `percent-encode` is enabled.
assert_eq!(&c.stripped().encoded().to_string(), "key%3F=value");
