Starting from this version the `CHANGELOG.md` file is the canonical
source for the list of significant changes. See the file for details.
Fixes#146.
Fixes#159.
This removes `Datelike::isoweekdate` in favor of `Datelike::iso_week`.
The original `isoweekdate` was not named in accordance with the style
guide and also used to return the day of the week which is already
provided by `Datelike::weekday`. The new design should be more
reasonable.
Note that we initially do not implement any public constructor for
`IsoWeek`. That is, the only legitimate way to get a new `IsoWeek` is
from `Datelike::iso_week`. This sidesteps the issue of boundary values
(for example the year number in the maximal date will overflow in
the week date) while giving the same power as the original API.
Partially accounts for #139. We may add additional week types
as necessary---this is the beginning.
There used to be multiple modules like `chrono::datetime` which only
provide a single type `DateTime`. In retrospect, this module structure
never reflected how people use those types; with the release of 0.3.0
`chrono::prelude` is a preferred way to glob-import types, and due to
reexports `chrono::DateTime` and likes are also common enough.
Therefore this commit removes those implementation modules and
flattens the module structure. Specifically:

All internal documentation links have been updated (phew!) and
verified with LinkChecker [1]. Probably we can automate this check
in the future.
[1] https://wummel.github.io/linkchecker/Closes#161. Compared to the original proposal, `chrono::naive` is
retained as we had `TsSeconds` types duplicated for `NaiveDateTime`
and `DateTime` (legitimately).
- Serde 1.0 is now supported. (#142)
Technically this is a breaking change, but the minor version was not
effective in avoiding dependency breakages anyway (because Cargo
will silently compile two versions of crates). Provided that this is
likely the last breakage from Serde, we tolerate
this more-than-last-minute change in this version.
- `Weekday` now implements `FromStr`, `Serialize` and `Deserialize`.
(#113)
- Fixed a bug that the leap second can be mapped wrongly
in the local tz with some conditions. (#130)
- Some changes to the tests to avoid previously known issues.
Note that the actually published version is very slightly different
from the repository because no published version of bincode supports
Serde 1.0 right now.
So this is a much delayed major release, but this should not really
change how you use Chrono---only the "required" breakages have been
done (e.g. anything hindering API evolution). The "big" release used to
be 0.3, but due to the dependency changes we are forced to push that to
0.4. I've took this opportunity to push all known planned breaking
changes to 0.3, so this should be quite stable for a moment.
See `CHANGELOG.md` for the full list of changes, but most importantly:
- `chrono::prelude` module has been added for proper glob imports.
- `FixedOffset` is now the official "value" type for time zone offsets.
- Serde 0.9 support has landed, and serialization format used by
rustc-serialize and Serde has been now synchronized.
- Formatting items have been slightly adjusted to be future-proof.
Fixes#126.
This may sound strange, but the final type for the offset "value" was
originally `time::Duration` (returned by `Offset::local_minus_utc`).
This caused a lot of problems becaus adding `Duration` fully interacts
with leap seconds and `Duration` itself is somewhat deprecated.
This commit entirely replaces this role of `Duration` with
`FixedOffset`. So if we had `Offset` and `Duration` to represent
the "storage" offset type and the offset "value" in the past,
we now have `Offset` and `FixedOffset`. Storage-to-value conversion is
called to "fix" the offset---an apt term for the type.
The list of actual changes:
- The time zone offset is now restricted to UTC-23:59:59 through
UTC+23:59:59, and no subsecond value is allowed. As described above,
`FixedOffset` is now fully used for this purpose.
- One can now add and subtract `FixedOffset` to/from timelike values.
Replaces a temporary `chrono::offset::add_with_leapsecond` function.
Datelike & non-timelike values are never affected by the offset.
- UTC and local views to `Date<Tz>` are now identical. We keep
relevant methods for the consistency right now.
- `chrono::format::format` now receives `FixedOffset` in place of
`(Old)Duration`.
- `Offset` now has a `fix` method to resolve, or to "fix" the
"storage" offset (`Offset`) to the offset "value" (`FixedOffset`).
- `FixedOffset::{local_minus_utc, utc_minus_local}` methods are added.
They no longer depend on `Duration` as well.
Due to the backward compatibility we won't be going to remove support
for `time::Duration` in 0.3, and the initial 0.3.0 release won't have
proper `std::time::Duration` support (haven't finalized the logics).
However we will reserve proper names and signatures for the upcoming
`std::time::Duration` support---the "older" duration type will be
referred as "signed" in the names.
- Added a `chrono::prelude` module. This does not have the (old)
`Duration` type reexported, so the documentation has now correctly
replaced all occurrences of `chrono::Duration`. The existing
`chrono::Duration` reexport itself remains for the compatibility.
- Avoided using a plain `Duration` type in the signature, to avoid
any ambiguity.
- Renamed `checked_{add,sub}` to `checked_{add,sub}_signed`.
- Subtraction operator between two instants has been removed and
replaced with `signed_duration_since`. This follows the naming
chosen by `std::time::SystemTime` etc., and the version for newer
`std::time::Duration` will be named to `duration_since`.
All CI accounts are now moved to the new organization (unfortunately
Appveyor does not automatically move the build history though).
Since it's a mess to redirect everything to chronotope.github.io,
I've taken this as an opportunity to switch to docs.rs---this seems
to be better than the manual management nowadays.
Updated other files as accordingly.
The ISO 8601 format includes both "nominal" (year, month, week, and
day) and "accurate" (hour, minute, and second) components. However, the
`Duration` type only represents an "accurate" duration because
arithmetic with nominal components is not defined in ISO 8601.
- Serde 0.8 is now supported. (#86)
- The deserialization implementation for rustc-serialize now properly
verifies the input. Also tons of tests have been added. (#42)
- Tons of documentation updates! (#77, #78, #80, #82 and my own
changes as well)
- `DateTime::timestamp_subsec_{millis,micros,nanos}` methods have
been added. (#81)
- When the system time records a leap second,
the nanosecond component was mistakenly reset to zero. (#84)
- `Local` offset misbehaves in Windows for August and later,
due to the long-standing libtime bug (dates back to mid-2015).
Workaround has been implemented. (#85)
- The main documentation (`src/lib.rs` AND `README.md`) now properly
link to other types when rendered.
- The role of `TimeZone` trait is explained more thoroughly.
(Hopefully) fixes#82.
- `%.6f` and `%.9f` used to print only three digits
when the nanosecond part is zero. (#71)
- The documentation for `%+` has been updated
to reflect the current status. (#71)
- Added `%.3f`, `%.6f` and `%.9f` specifier for formatting fractional seconds
up to 3, 6 or 9 decimal digits. This is a natural extension to the existing `%f`.
Note that this is (not yet) generic, no other value of precision is supported. (#45)
- Forbade unsized types from implementing `Datelike` and `Timelike`.
This does not make a big harm as any type implementing them should be already sized
to be practical, but this change still can break highly generic codes. (#46)
- Fixed a broken link in the `README.md`. (#41)
- Tons of supporting examples for the documentation have been added. More to come.

```
...because of:
https://github.com/rust-lang/rfcs/pull/1214
- Added padding modifiers `%_?`, `%-?` and `%0?`.
- Added new specifiers `%:z` and `%.f`.
- When `%s` specifier is used with a time zone, the time zone offset was
ignored. This has been fixed.
- Several documentation fixes including the misleading presence of
colons in the `%z` specifier. `%:z` was introduced partly due to this.
- `NaiveDateTime +/- Duration` or `NaiveTime +/- Duration` could
have gone wrong when the `Duration` to be added is negative and
has a fractional second part.
This was caused by an underflow in the conversion from `Duration`
to the parts; the lack of tests for this case allowed a bug.
A regression test has been added to avoid further bugs. (#37)
- This version is finally beta-compatible.
This introduces a slight incompatibility, namely, due to
the rewired reexport for `chrono::Duration` (which now comes
from crates.io `time` crate).
- The optional dependency on `rustc_serialize` and relevant
`Rustc{En,De}codable` implementations for supported types
has been added. You will need the `rustc-serialize` Cargo
feature to use them.
- Many `std::num` traits are removed and replaced with
the external `num` crate. For time being, thus, Chrono will
require the dependency on `num`. This is expected to be temporary
however.
- Replaced `thread::scoped` with `thread::spawn` to cope with
a rare de-stabilization event.
- `#[deprecated]` is (ironically) deprecated with user crates.
All uses of them have been replaced by doc comments.
- Feature flags are now required on the doctests.
- New lints for trivial casts. We are now not going to change
the internal implementation type for `NaiveDate`, so that's fine.
- `DateTime<Tz>` and `Date<Tz>` is now `Copy`/`Send` when
`Tz::Offset` is `Copy`/`Send`. The implementations for them were
mistakenly omitted. Fixes#25.
- `Local::from_utc_datetime` didn't set a correct offset.
The tests for `Local` were lacking. Fixes#26.
`Time` with an associated time zone is in principle possible, but
in practice it can only meaningfully constructed from an existing
`DateTime`. this makes it hard to implement other operations
natural to `NaiveTime` for `Time` (e.g. `with_*` methods), so
we simply let it go.
migration path: if you *do* happen to use `Time`, don't panic!
every operation possible to `Time` is much more possible to
`NaiveTime`. if you have to deal with a local time, first combine
it with a `NaiveDate`, convert it via `TimeZone::from_local_datetime`
then extract `Time` part again.
- We have splitted `Offset` into `Offset` and `OffsetState` (name
changes in consideration). The former is used to construct and convert
local or UTC date, and the latter is used to store the UTC offset
inside constructed values. Some offsets are their own states as well.
- This uses lots of associated types which implementation is still in
flux. Currently it crashes with debuginfo enabled. We've temporarily
disabled debuginfo from `Cargo.toml`.
- This technically allows a conversion to the local time, but not yet
tested.
so that we can safely implement `FromStr` traits for those types.
also updates READMEs and rewires `%+` specifier of `StrftimeItems`
to a new RFC 3339 formatting item.
this new module encompasses John Nagle's original RFC 2822 and 3337
parsers, updated to fully compatible to the actual standard.
the contributed `parse` module has been merged into it.
Basically, this should close#12 when officially released.
- Formatting syntax is now refactored out of the rendering logic.
The main syntax is available in the `format::strftime` module,
which also serves as a documentation for the syntax.
- A parser (modelled after `strptime(3)`) has been implemented.
See the individual commits for the detailed implementation.
- There are two ways to get a timezone-aware value from a string:
`Offset` or `DateTime<FixedOffset>`. The former should be used
when the offset is known in advance (e.g. assume the local date)
while the latter should be used when the offset is unknown.
Naive types have a simple `from_str` method.
- There are some known problems with the parser (even after
tons of tests), which will be sorted out in 0.2. Known issues:
- This does not exactly handle RFC 2822 and RFC 3339, which
subtly differs from the current implementation in
case-sensitivity, whitespace handling and legacy syntax.
I'd like to integrate #24 for this cause.
- Time zone names are not recognized at all. There is even
no means to get a name itself, not sure about the resolution.
- `Parsed` does *not* constrain `year` to be non-negative,
so manually prepared `Parsed` may give a negative year.
But the current verification pass may break such cases.
- I absolutely don't know about the parser's performance!
- `AUTHORS.txt` has been added, for what it's worth.
- Every type modulo `LocalResult` and `Offset` now implements
`std::fmt::String`, so `.to_string()` can be used.
The exact format has been changed for better looking output.
- `std::fmt::Show` are intended for "stricter" output,
which mostly means the strict ISO 8601 format.
`DelayedFormat` also implements this, but only for inspection.
- `Offset` should implement `Show` but can omit `String`.
The old `name` method is merged into `String` implementations.
- Feature flags used are all accepted.
- Orphan check workaround is no longer required.
- Impl reachability rules prevent the addition of `Duration + others`,
as `Duration` is not implemented in this crate. Removed the impl;
use `others + Duration` as a workaround.
