* Add functions to get milli/micro/nano-seconds from a DateTime
Using the underlying naive::NaiveTime fractional part, we compute
the number of milli/micro/nano-seconds since the last second boundary.
The reason for not computing elapsed time since 1970 is because we
would hit potential issues of i64s not being large enough (the range
would be strictly smaller than the 64bit-timestamp range, causing
compatibility issues).
* Rename subsecond functions
Renamed accessors to subsec_{nano,micro,milli}, as suggested
in pull request comment. Also added warnings for leap second
consitions causing these values to exceed the normal range
of 0..10^n.
Fixed editor's previous obnoxious whitespace changes.
The exact condition is that the `Duration` to be added is negative
and has a fractional second part. This was not a problem when
`Duration` was Chrono's own type, but a new code for external (then
libstd, now libtime) `Duration` was not tested for this condition
by accident. Consequently this condition caused an underflow in
the fractional part, resulting in a slight inaccuracy.
Fixes#37.
- 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All uses of them have been replaced by doc comments.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.
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.
also, previously `Numeric::Nanosecond` had a special left-aligned
parsing behavior. this commit replaces that with a newly designated
`Fixed::Nanosecond` which also handles an empty string which is
possible with an integral number of seconds.
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.
