c.make_permanent();
assert_eq!(c.max_age(), Some(Duration::days(365 * 20)));

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

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.

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>

Available on crate feature percent-encode only.

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");
