Bumps jiff from 0.2.1 to 0.2.2.

Changelog

Sourced from jiff's changelog.

0.2.2 (2025-03-06)

This release of Jiff includes a new opt-in proc macro for embedding a TimeZone into your binary. Just enable Jiff's static feature, and this will print the current time in the America/New_York time zone:

use jiff::{
    tz::{self, TimeZone},
    Timestamp,
};
fn main() {
static TZ: TimeZone = tz::get!("America/New_York");
let zdt = Timestamp::now().to_zoned(TZ.clone());
println!("{zdt}");
}

This enables TimeZone to be meaningfully used in core-only environments, even when dynamic memory allocation isn't available.

This release also features a number of performance improvements for time zone lookups. In some cases, the improvement is significant (by an order of magnitude).

Additionally, the IANA Time Zone Database embedded into jiff-tzdb now uses "rearguard" semantics. This means that the boolean flag indicating whether daylight saving time is active or not (only accessible via TimeZone::to_offset_info) will respect the actual definition of daylight saving time. (This is relevant, for example, for time zones like Europe/Dublin, where their summer time is legally known as their standard time, but is in effect daylight saving time.)

Enhancements:

  • #256: Add tz::{get,include} macros for time zone support in core-only environments.
  • #258: Switch to rearguard tzdb data in jiff-tzdb and document it.
  • #259: De-duplicate TZif data in jiff-tzdb.
  • #273: Add "crate features" documentation to jiff-sqlx and jiff-diesel.
  • #277: Document semver guarantee for error conditions on Timestamp constructors.
  • #277: Greatly optimize time zone lookups (for both timestamps and civil datetimes).
