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();
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

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());
assert!(expires.is_datetime());

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());
assert!(!expires.is_session());

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

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();
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);
