Something that wasn't part of this PR: the work to support nested
`Option<[ChronoType]>` was merged without being adjusted for the no-std
support
And now there are some unused import warnings because they need to get
configged out.
The Item::Space calls str::trim_left and Item::Numeric also calls
str::trim_left before doing anything else, so there is no need to
have Item::Space before Item::Numeric.
Speeds up parsing:

datetime::tests::bench_datetime_from_str 582 448 -134 -23.02% x 1.30

The parse::parse and format::format functions accepted Iterator of owned
Items. While it is sometimes convenient to pass in the owned values,
neither of the functions really need to own them, so references would
be enough. The Borrow trait allows us to pass in Iterator over values,
references, boxes, etc.
According to RFC 1105 this is a minor change, because it shouldn't break
any existing code. And chrono is in pre-1.0 version anyway.
This allows us to remove multiple cloned() calls which speeds up parsing
and formating:

The #[cfg(bench)] attribute does not exist and is always false. Lets
define a feature "bench" which can be used to enable benchmarks when
building with nightly.
The new wording tries to make clearer that those methods use a 1-based
numbering scheme.
This commit also includes a couple of drive-by cosmetic changes.
This adds a new `std` feature to chrono that is enabled by default. By
deactivating this feature via `default-features = false` you can now use
chrono in applications that don't use the standard library. The `serde`
feature is supported as well.
Resolves#336
This contructor allows you to make a NaiveDate by specifying eg. "the
2nd Friday of March 2017". It contains a couple of panics, but these
are consistent with the behaviour of the other NaiveDate constructors.
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.
Now (assuming clippy is right) all (~100) uses of ` as ` in the code are
actually doing casts that could potentially silently lose data. Woooo?
At least this means that new `as`s can be extra-scrutinized, and we should
probably be adding debug_assert!s for the casts in real code.
The implementation is identical to how #[derive] would do it, and we use the
implementation to add some documentation warning people not to use items with
nanosecond-level precision in hash maps unless they're sure that's what they
want.
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.
Linkchecker recognizes the distinction between internal and external
links (which are not checked by default), and considers URLs which
does not have the starting URL base as a prefix internal...
This commit has been verified against a proper set of options to
Linkchecker, but there are several false positives (for our purposes)
which would make the automated checking not as effective. </rant>
