Release Notes

time-rs/time (time)

v0.3.46

Compare Source

Added
  • All possible panics are now documented for the relevant methods.

  • The need to use #[serde(default)] when using custom serde formats is documented. This applies
    only when deserializing an Option<T>.

  • Duration::nanoseconds_i128 has been made public, mirroring
    std::time::Duration::from_nanos_u128.

  • Various methods for truncating components have been added, avoiding the need to call the fallible
    replace methods multiple times.

    For PrimitiveDateTime, UtcDateTime, and OffsetDateTime:

    • truncate_to_day

    For Time, PrimitiveDateTime, UtcDateTime, and OffsetDateTime:

    • truncate_to_hour
    • truncate_to_minute
    • truncate_to_second
    • truncate_to_millisecond
    • truncate_to_microsecond
Changed
  • The minimum supported Rust version is now 1.88.0.
  • Significant performance gains in numerous locations. No public APIs were changed or removed as
    part of this.
  • The size of error::ComponentRange, along with types that contain it, has been significantly
    reduced.
Fixed
  • The PartialOrd and Ord implementations of UtcOffset now return the expected result.

v0.3.45

Compare Source

Added
  • time::format_description::StaticFormatDescription type alias for &'static [BorrowedFormatItem<'static>]. This is the type returned by the
    time::macros::format_description! macro.
Changed
  • The minimum supported Rust version is now 1.83.0.
  • All floating point methods on Duration are now const fn.
  • All setters on Parsed are now const fn.
  • The serde dependency has been replaced with serde_core, This reduces compile times by not
    including unused parts of serde.
  • Date::from_julian_day uses a new algorithm, resulting in an approximately 16% performance
    improvement. This method is used internally by numerous other methods.
  • util::is_leap_year uses a new algorithm, resulting in an approximately 8% performance
    improvement.

v0.3.44

Compare Source

Fixed
  • Comparisons of PrimitiveDateTime, UtcDateTime, and OffsetDateTime with differing signs (i.e.
    one negative and one positive year) would return the inverse result of what was expected. This was
    introduced in v0.3.42 and has been fixed.
  • Type inference would fail due to feature unification when wasm-bindgen enabled serde_json.
    This has been fixed by explicitly specifying the type in the relevant locations.

v0.3.43

Compare Source

Added
  • Support for rand 0.9
Fixed
  • In the convert module, any use of per with types that were not the same (such as
    Nanosecond::per(Second)) would not compile due to a bug. This has been fixed.

v0.3.42

Compare Source

Added
  • Time::duration_until
  • Time::duration_since
  • per_t method for all types in time::convert. This is similar to the existing per method, but
    can return any of the primitive numeric types that can represent the result. This will cut down on
    as casts while ensuring correctness. Type inference isn't perfect, so you may need to provide a
    type annotation in some situations.
  • impl PartialOrd for Month and impl Ord for Month; this assumes the months are in the same year
  • SystemTimeExt trait, adding methods for checked arithmetic with time::Duration and obtaining
    the difference between two SystemTimes as a time::Duration
  • Permit using UtcDateTime with rand (this was inadvertently omitted previously)
  • impl core::error::Error for all error types (now available when the std feature is disabled)
  • MacOS can now obtain the local UTC offset in multi-threaded programs as the system APIs are
    thread-safe.
  • #[track_caller] has been added to all relevant methods.
Changed
  • The minimum supported Rust version is now 1.81.0.
  • The dependency on itoa has been removed, as the standard library now has similar functionality
    by default.
  • Formatting a component that involves a floating point number is now guaranteed to be
    deterministic, avoiding any subtle differences between platforms or compiler versions.
Fixed
  • Serializing timestamps with nanosecond precision should always emit the correct value.
    Previously, it could be off by one nanosecond due to floating point imprecision.
  • A previously unknown bug in OffsetDateTime::to_offset and UtcDateTime::to_offset has been
    fixed. The bug could result in a value that was invalid. It was unlikely to ever occur in
    real-world code, as it involved passing a UTC offset that has never been used in any location.
Miscellaneous
  • The amount of code generated by macros has been massively reduced, on the order of 65-70% for
    typical use cases of format_description!.
  • Significant performance gains for comparisons of Time, PrimitiveDateTime, UtcDateTime, and
    OffsetDateTime. The first three have gains of approximately 85% (i.e. 6× faster).
  • Nearly all methods are #[inline].
