And fail CI in the future if `make readme` isn't run when it is needed.
CC conversation in #185, where the README didn't get updated for a year after
lib.rs was improved.
Unfortunately due to rust-lang/rust#39935 placing the annotation on the `impl`s
of `Encodable`/`Decodable` for the various items have no effect whatsoever, so
we need to place it on some type that chrono actually uses internally. The only
*type* that I can find that only exists for rustc-serialize only is the
`TsSeconds` struct.
So, marking TsSeconds deprecated causes Chrono's internal uses of `TsSeconds`
to emit deprecation warnings, both in our builds and for packages that specify
Chrono as a dependency with the `rustc-serialize` feature active. This means
that the current commit will cause a `warning: use of deprecated item:
RustcSerialize will be removed before chrono 1.0, use Serde instead` to appear
in `cargo build` output.
Unfortunately I don't think that it's possible for downstream crates to disable
the warning the warning in any way other than actually switching to Serde or
using an older chrono. That's the reason for all the `#[allow(deprecated)]`
through the code, it means that the warning appears almost exactly once,
instead of dozens of times.
Rather than the `num` meta-crate, use `num-integer` and `num-traits`
without default features to make them `#[no_std]`. `num-iter` is
just a dev-dependency now for a few test cases.
The only public change is the `impl FromPrimitive for Weekday`, but this
is still the same exact trait that `num` re-exports, so this is not a
breaking change.
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.
