v0.3.29

Compare Source

Added

• Niche value optimization for Date has been added. Both Date and Option<Date> are four bytes.

• Unit conversions have been added. It is now possible to write Second::per(Day), which returns the number of seconds in one day. See the types in the [time::convert module][time::convert module] for more information.

Changed

• The diagnostic for --cfg unsound_local_offset has been removed.
• #![feature(no_coverage)] was previously used internally for code coverage. It is no longer used, so it has been removed.
• The default value for modifier::OffsetHour has been changed. This was unintentionally changed in v0.3.17 and went unnoticed until now. The sign is now only present if needed by default, as was the case previously. This does not affect any situation where format_description! or format_description::parse is used.

Fixed

• Adding or subtracting a std::time::Duration to/from an OffsetDateTime will not result in integer overflow internally. It will still panic if the result is out of range.

v0.3.28

Compare Source

Added

• More additional constants for the well-known Iso8601 format description have been added. This avoids the need to manually configure the format.
• An [end] component has been added. This is ignored during formatting, but is used to indicate the end of input when parsing. If any input remains after this component, an error is returned. This is useful when using the [first] component, as it avoids the need to reorder variants.

Changed

• The exemption for MacOS introduced in 0.3.20 has been removed. This is because some supported versions of MacOS do not meet the requirements for the exemption.
• The UnexpectedTrailingCharacters error variant has been moved to ParseFromDescription. All previously-existing locations of this variant have been deprecated and will no longer be returned.

v0.3.27

Compare Source

This sets the serde dependency requirement to >= 1.0.184 where the binaries have been removed.

v0.3.26

Compare Source

This release contains only a single change. serde is required to be a version prior to 1.0.171. This is due to the decision by the maintainer of serde to include pre-built binaries that are executed without the end user's knowledge. As of the time of publishing, the included binary has not even been reproduced. This is a security risk, and the time project strongly opposes this decision. While this may break some users' builds due to conflicting versions, it is a necessary step to ensure the security.

v0.3.25

Compare Source

Fixed

• Methods such as Time::replace_milliseconds would panic on some out-of-range values. This has been fixed.

v0.3.24

Compare Source

Added

• The subsecond component is taken into account when parsing the unix_timestamp component. If data is conflicting, the subsecond value takes precedence.
• Parsing a Time with only the hour component is now supported. The minute and second, and subsecond components are assumed to be zero.

Changed

• The minimum supported Rust version is now 1.67.0.
• The debug output for Parsed has been improved.
• When parsing, invalid values are now rejected sooner. Previously, the entire input would be parsed before being rejected in the final step. Now, invalid values are rejected as soon as they are encountered. This affects the error variant returned, which may cause minor breakage for any code (incorrectly) relying on the exact error variant.
• When parsing a Time, an error is returned if components are present but not consecutive. For example, if hours and seconds are present, minutes will not be assumed to be zero.

Fixed

• The implementation of Duration::checked_div could return a slightly incorrect result in some cases. This has been fixed.

v0.3.23

Compare Source

Added

• Date::next_occurrence
• Date::prev_occurrence
• Date::nth_next_occurrence
• Date::nth_prev_occurrence
• Weekday::nth_prev
• Month::nth_next
• Month::nth_prev

Changed

The minimum supported Rust version policy has been updated. See the README for details.

Fixed

• Duration::abs correctly returns Duration::MAX when near the minimum value. The nanoseconds value was previously incorrect.
• Compliance with ISO 8601 has been improved. Previously, a UTC offset would be incorrectly rejected in some cases.

v0.3.22

Compare Source

Added

• OffsetDateTime::checked_to_offset

v0.3.21

Compare Source

Added

• Any formattable/parsable type can now be used with the time::serde::format_description! macro.
• Weekday::nth_next

Changed

• The minimum supported Rust version is now 1.65.0.

v0.3.20

Compare Source

Changed

• The minimum supported Rust version is now 1.63.0.
• On Unix-based operating systems with known thread-safe environments, functions obtaining the local offset no longer require a check that the program is single-threaded. This currently includes MacOS, illumos, and NetBSD.

Added

• [ignore] component in format descriptions. A count modifier is required, indicating the number of bytes to ignore when parsing.
• [unix_timestamp] component in format descriptions. This is currently only usable with OffsetDateTime. Users can choose between seconds, milliseconds, microseconds, and nanoseconds, and whether the sign is mandatory or optional.

Fixed

• The API for declaring soundness now uses stricter atomic orderings internally.

v0.3.19

Compare Source

Fixed

This includes the update to the format_description! macro, which was supposed to be included in 0.3.18.

v0.3.18

Compare Source

Changed

• The minimum supported Rust version is now 1.62.0.

Added

• [first] and [optional] items can now be included in format descriptions. To parse this at runtime, you must use the format_description::parse_owned method.
• format_description::parse_borrowed
• An API has been added to opt out of soundness checks for obtaining the local offset. This replaces the previous, officially unsupported RUSTFLAGS="--cfg unsound_local_offset". End users may call time::util::local_offset::set_soundness(time::util::local_offset::Soundness::Unsound). This method is unsafe because it enables undefined behavior if its safety requirements are not upheld. Note that libraries must not set this to Unsound, as it is impossible for a library to guarantee end users uphold the required invariants.

Fixed

• Correctly parse offset sign when hour is zero. The parse was previously unconditionally positive, even if the sign indicated otherwise.
• Compilation is fixed for WebAssembly.

v0.3.17

Compare Source

Changed

• The amount of code generated by time::serde::format_description! is reduced if not all feature flags are active.
• cargo test --tests works with any configuration of feature flags. This occurs by spawning a subprocess that passes --all-features. cargo test --doc works with most combinations of feature flags, including the default. The combination of these changes means that crater will now run on time.
• libc and num_threads are only included as dependencies when needed. They were previously unconditionally included.

Added

• time::format_description::parse_owned, which returns an OwnedFormatItem. This avoids "lifetime hell", where all your structs now need a lifetime because a single field has one. Note that when possible, the borrowed format item (just called FormatItem) is still preferred, as it has significantly fewer allocations. The new OwnedFormatItem is usable for both formatting and parsing, as you would expect.

Compatibility

• The parser for runtime format descriptions has been rewritten. A side effect of this is that some errors have slightly changed. No existing API has been altered, so this is not a breaking change. However, you may notice different errors, which are hopefully better! The parser for compile-time format descriptions has not yet been swapped out. If you notice any bugs, please file an issue.

v4

Compare Source

• Support fetching without the --progress option
• Update to node20

v0.3.30

Compare Source

Added

• powerfmt::smart_display::SmartDisplay has been added for the main types in the library. These implementations ensure that values follow the requested fill, width, and alignment when using format! or similar macros. Display is implemented in terms of SmartDisplay.

Fixed

• Large values no longer wrap around in release mode when using NumericalDuration or NumericalStdDuration.
