Enum cookie::Expiration

source ·
pub enum Expiration {
    DateTime(OffsetDateTime),
    Session,
}
Expand description

A cookie’s expiration: either session or a date-time.

An Expiration is constructible via Expiration::from() with an Option<OffsetDateTime> or an OffsetDateTime:

  • None -> Expiration::Session
  • Some(OffsetDateTime) -> Expiration::DateTime
  • OffsetDateTime -> Expiration::DateTime
use cookie::Expiration;
use time::OffsetDateTime;

let expires = Expiration::from(None);
assert_eq!(expires, Expiration::Session);

let now = OffsetDateTime::now_utc();
let expires = Expiration::from(now);
assert_eq!(expires, Expiration::DateTime(now));

let expires = Expiration::from(Some(now));
assert_eq!(expires, Expiration::DateTime(now));

Variants§

§

DateTime(OffsetDateTime)

Expiration for a “permanent” cookie at a specific date-time.

§

Session

Expiration for a “session” cookie. Browsers define the notion of a “session” and will automatically expire session cookies when they deem the “session” to be over. This is typically, but need not be, when the browser is closed.

Implementations§

source§

impl Expiration

source

pub fn is_datetime(&self) -> bool

Returns true if self is an Expiration::DateTime.

§Example
use cookie::Expiration;
use time::OffsetDateTime;

let expires = Expiration::from(None);
assert!(!expires.is_datetime());

let expires = Expiration::from(OffsetDateTime::now_utc());
assert!(expires.is_datetime());
source

pub fn is_session(&self) -> bool

Returns true if self is an Expiration::Session.

§Example
use cookie::Expiration;
use time::OffsetDateTime;

let expires = Expiration::from(None);
assert!(expires.is_session());

let expires = Expiration::from(OffsetDateTime::now_utc());
assert!(!expires.is_session());
source

pub fn datetime(self) -> Option<OffsetDateTime>

Returns the inner OffsetDateTime if self is a DateTime.

§Example
use cookie::Expiration;
use time::OffsetDateTime;

let expires = Expiration::from(None);
assert!(expires.datetime().is_none());

let now = OffsetDateTime::now_utc();
let expires = Expiration::from(now);
assert_eq!(expires.datetime(), Some(now));
source

pub fn map<F>(self, f: F) -> Self

Applied f to the inner OffsetDateTime if self is a DateTime and returns the mapped Expiration.

§Example
use cookie::Expiration;
use time::{OffsetDateTime, Duration};

let now = OffsetDateTime::now_utc();
let one_week = Duration::weeks(1);

let expires = Expiration::from(now);
assert_eq!(expires.map(|t| t + one_week).datetime(), Some(now + one_week));

let expires = Expiration::from(None);
assert_eq!(expires.map(|t| t + one_week).datetime(), None);
