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.
Due to the obvious lack of time zone information in `SystemTime`,
`SystemTime` can only be converted to `DateTime<Utc>` (in UTC) or
`DateTime<Local>` (in the local time zone), while any `DateTime<Tz>`
can be converted to `SystemTime`.
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>
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).
I think it's a terrible API, but AFAIK rustc-serialize doesn't support anything
like serde's `with` attribute.
I think it would be better to just not include this API at all and require that
people who want to use this move to serde, which is the recommended rust
encoding/decoding library.
This introduces a newtype around DateTime and NaiveDateTime that deserlization
is implemented for.
There are two advantages to this over the previous implementation:
* It is expandable to other timestamp representations (e.g. millisecond and
microsecond timestamps)
* It works with RustcSerialize::Decodable. AFAICT Decodable will error if you
try to call more than one of the `read_*` functions in the same `decode`
invocation. This is slightly annoying compared to serde which just calls the
correct `visit_*` function for whatever type the deserializer encounters.
On the whole I think that I prefer this to the previous implementation of
deserializing timestamps (even though I don't care about RustcSerialize in the
post-1.15 world) because it is much more explicit.
On the other hand, this feels like it's introducing a lot of types, and
possibly making downstream crates introduce a variety of different structs for
ser/de and translating into different struct types.
Timestamps are defined in terms of UTC, so what this does is, if we encounter
an integer instead of a str, create a FixedOffset timestamp with an offset of
zero and create the timestamp from that.
- 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.
