Struct DeltaCookie

pub(crate) struct DeltaCookie {
    pub cookie: Cookie<'static>,
    pub removed: bool,
}

A DeltaCookie is a helper structure used in a cookie jar. It wraps a Cookie so that it can be hashed and compared purely by name. It further records whether the wrapped cookie is a “removal” cookie, that is, a cookie that when sent to the client removes the named cookie on the client’s machine.

Fields

cookie: Cookie<'static>

removed: bool

Implementations

impl DeltaCookie

pub fn added(cookie: Cookie<'static>) -> DeltaCookie

Create a new DeltaCookie that is being added to a jar.

pub fn removed(cookie: Cookie<'static>) -> DeltaCookie

Create a new DeltaCookie that is being removed from a jar. The cookie should be a “removal” cookie.

Methods from Deref<Target = Cookie<'static>>

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.

Does not strip surrounding quotes. See Cookie::value_trimmed() for a version that does.

Example

use cookie::Cookie;

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

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

pub fn value_trimmed(&self) -> &str

Returns the value of self with surrounding double-quotes trimmed.

This is not the value of the cookie (that is Cookie::value()). Instead, this is the value with a surrounding pair of double-quotes, if any, trimmed away. Quotes are only trimmed when they form a pair and never otherwise. The trimmed value is never used for other operations, such as equality checking, on self.

Example

use cookie::Cookie;
let c0 = Cookie::new("name", "value");
assert_eq!(c0.value_trimmed(), "value");

let c = Cookie::new("name", "\"value\"");
assert_eq!(c.value_trimmed(), "value");
assert!(c != c0);

let c = Cookie::new("name", "\"value");
assert_eq!(c.value(), "\"value");
assert_eq!(c.value_trimmed(), "\"value");
assert!(c != c0);

let c = Cookie::new("name", "\"value\"\"");
assert_eq!(c.value(), "\"value\"\"");
assert_eq!(c.value_trimmed(), "value\"");
assert!(c != c0);

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 name_value_trimmed(&self) -> (&str, &str)

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

Example

use cookie::Cookie;

let c = Cookie::new("name", "\"value\"");
assert_eq!(c.name_value_trimmed(), ("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 partitioned(&self) -> Option<bool>

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

Note: This cookie attribute is an HTTP draft! Its meaning and definition are not standardized and therefore subject to change.

Example

use cookie::Cookie;

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

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

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

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

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

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).build();
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).build();
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 set_name<N: Into<Cow<'c, str>>>(&mut self, name: N)

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");
assert_eq!(c.name(), "foo");

pub fn set_value<V: Into<Cow<'c, str>>>(&mut self, value: V)

Sets the value of self to value.

Example

use cookie::Cookie;

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

c.set_value("bar");
assert_eq!(c.value(), "bar");

pub fn set_http_only<T: Into<Option<bool>>>(&mut self, value: T)

Sets the value of http_only in self to value. If value is None, the field is unset.

Example

use cookie::Cookie;

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

c.set_http_only(true);
assert_eq!(c.http_only(), Some(true));

c.set_http_only(false);
assert_eq!(c.http_only(), Some(false));

c.set_http_only(None);
assert_eq!(c.http_only(), None);

pub fn set_secure<T: Into<Option<bool>>>(&mut self, value: T)

Sets the value of secure in self to value. If value is None, the field is unset.

Example

use cookie::Cookie;

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

c.set_secure(true);
assert_eq!(c.secure(), Some(true));

c.set_secure(false);
assert_eq!(c.secure(), Some(false));

assert_eq!(c.secure(), None);

pub fn set_same_site<T: Into<Option<SameSite>>>(&mut self, value: T)

Sets the value of same_site in self to value. If value is None, the field is unset. If value is SameSite::None, the “Secure” flag will be set when the cookie is written out unless secure is explicitly set to false via Cookie::set_secure() or the equivalent builder method.

Example

use cookie::{Cookie, SameSite};

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

c.set_same_site(SameSite::None);
assert_eq!(c.same_site(), Some(SameSite::None));
assert_eq!(c.to_string(), "name=value; SameSite=None; Secure");

c.set_secure(false);
assert_eq!(c.to_string(), "name=value; SameSite=None");

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

assert_eq!(c.to_string(), "name=value; SameSite=Strict");

c.set_same_site(None);
assert_eq!(c.same_site(), None);
assert_eq!(c.to_string(), "name=value");

pub fn set_partitioned<T: Into<Option<bool>>>(&mut self, value: T)

Sets the value of partitioned in self to value. If value is None, the field is unset.

Note: Partitioned cookies require the Secure attribute to be set. As such, Partitioned cookies are always rendered with the Secure attribute, irrespective of the Secure attribute’s setting.

Note: This cookie attribute is an HTTP draft! Its meaning and definition are not standardized and therefore subject to change.

Example

use cookie::Cookie;

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

c.set_partitioned(true);

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

pub fn unset_path(&mut self)

Unsets the path of self.

Example

use cookie::Cookie;

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

c.set_path("/");
assert_eq!(c.path(), Some("/"));

c.unset_path();
assert_eq!(c.path(), None);

pub fn set_domain<D: Into<Cow<'c, str>>>(&mut self, domain: D)

Sets the domain of self to domain.

Example

use cookie::Cookie;

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

c.set_domain("rust-lang.org");

pub fn unset_domain(&mut self)

Unsets the domain of self.

Example

use cookie::Cookie;

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

c.unset_domain();
assert_eq!(c.domain(), None);

pub fn set_expires<T: Into<Expiration>>(&mut self, time: T)

Example

use cookie::{Cookie, Expiration};
use cookie::time::{Duration, OffsetDateTime};

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

let mut now = OffsetDateTime::now_utc();
now += Duration::weeks(52);

c.set_expires(now);
assert!(c.expires().is_some());

c.set_expires(None);
assert_eq!(c.expires(), Some(Expiration::Session));

pub fn unset_expires(&mut self)

Unsets the expires of self.

Example

use cookie::{Cookie, Expiration};

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

assert_eq!(c.expires(), Some(Expiration::Session));

c.unset_expires();
assert_eq!(c.expires(), None);

pub fn make_permanent(&mut self)

Makes self a “permanent” cookie by extending its expiration and max age 20 years into the future.

Example

use cookie::Cookie;
use cookie::time::Duration;

let mut c = Cookie::new("foo", "bar");
assert!(c.expires().is_none());
assert!(c.max_age().is_none());

use cookie::Cookie;
use cookie::time::Duration;

let mut c = Cookie::new("foo", "bar");
c.make_permanent();
assert_eq!(c.max_age(), Some(Duration::days(365 * 20)));

c.make_removal();
assert_eq!(c.value(), "");
assert_eq!(c.max_age(), Some(Duration::ZERO));

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

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 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("/").build();
assert_eq!(&c.stripped().to_string(), "key?=value");
