- 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All uses of them have been replaced by doc comments.
This is due to somewhat ambiguous semantics of `Date`. It cannot
really constructed without an intermediate `DateTime` much like
the removed `Time`, but it is much more useful than `Time` so
we need some reasonable meaning to it. This commit clarifies
that meaning and corrects some problems around it:
- The date itself is timezone-agnostic unless the timezone itself
has an offset equal to or greater than one day. In all current
time zones, the date conversion should be a no-op.
- The date may be attached some offset; that offset should have
been occurred within the corresponding day in either the local
time or the UTC.
- `TimeZone` is free to assign the offset within this constraint.
For convenience, the current `Local` time zone assumes the local
midnight or the UTC midnight.
- `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.
this is partly because... we are using the simple name `timestamp`
in the `Parsed` anyway. that value is so widespread enough that
its name can be simply THE timestamp. old methods have been marked
deprecated.
- 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.
- Format string is internally represented as a series of formatting
items. Items can be directly given to now-public `format::format`
function as well.
- Format string parser is separated to `format::strftime` module.
This is to allow for potentional alternative formatting syntaxes.
- `DelayedFormat` now receives an iterator for formatting items.
- 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.
Added 'use' statements for cmd::Ordering, ops::{Add, Sub}, borrow::IntoCow, num::ToPrimitive
Changed deriving -> derive. Changed [x, ..N] -> [x; N].
Made format(f: &fmt::Formatter) return fmt::Result instead of
IoResult. Had to raise generic errors in a couple of cases where
IoResult's fields were being set (but these errors were being thrown
out anyway).
Temporarily set #![feature(old_orphan_check)] because
Thanks for @eddyb for explaining the format() situation.
- `Date/Time - Duration` is now supported. (duh!)
- `with_offset` methods have been added.
- `LocalResult` now implements common traits.
- `LocalResult` has several methods to propagate errors.
this makes the initialization from untrusted sources easier
(`off.ymd_opt(y,m,d).and_hms_opt(h,n,s).single()`).
- `num` dependency is gone. It was only used for floored division
and it is not hard to copy only that portion from num.
- `Duration + Date` (or so) was blocked by rust-lang/rust#7590,
which has been subsequently fixed.
- Removed unused `unsafe` checks.
`Duration` now has a `to_tuple` method which corresponds to
the original `(dur.ndays(), dur.nseconds(), dur.nnanoseconds())`.
new `num_*s()` methods in `Duration` always return the integral
number of specified units in the duration.

- added a new example.
- reexported all public APIs in the crate root.
- made all constructors fail on the invalid arguments by default;
`*_opt()` variants have been added for the original behavior.
- same for `DateZ::{succ,pred}`.
- fixed a missing overflow check from `TimeZ::from_hms_{milli,micro}`.
