Struct chrono::Date [] [src]

pub struct Date<Tz: TimeZone> { /* fields omitted */ }

ISO 8601 calendar date with time zone.

This type should be considered ambiguous at best, due to the inherent lack of precision required for the time zone resolution. For serialization and deserialization uses, it is best to use NaiveDate instead. There are some guarantees on the usage of Date<Tz>:

Methods

impl<Tz: TimeZone> Date<Tz>
[src]

[src]

Makes a new Date with given UTC date and offset. The local date should be constructed via the TimeZone trait.

[src]

Makes a new DateTime from the current date and given NaiveTime. The offset in the current date is preserved.

Panics on invalid datetime.

[src]

Makes a new DateTime from the current date, hour, minute and second. The offset in the current date is preserved.

Panics on invalid hour, minute and/or second.

[src]

Makes a new DateTime from the current date, hour, minute and second. The offset in the current date is preserved.

Returns None on invalid hour, minute and/or second.

[src]

Makes a new DateTime from the current date, hour, minute, second and millisecond. The millisecond part can exceed 1,000 in order to represent the leap second. The offset in the current date is preserved.

Panics on invalid hour, minute, second and/or millisecond.

[src]

Makes a new DateTime from the current date, hour, minute, second and millisecond. The millisecond part can exceed 1,000 in order to represent the leap second. The offset in the current date is preserved.

Returns None on invalid hour, minute, second and/or millisecond.

[src]

Makes a new DateTime from the current date, hour, minute, second and microsecond. The microsecond part can exceed 1,000,000 in order to represent the leap second. The offset in the current date is preserved.

Panics on invalid hour, minute, second and/or microsecond.

[src]

Makes a new DateTime from the current date, hour, minute, second and microsecond. The microsecond part can exceed 1,000,000 in order to represent the leap second. The offset in the current date is preserved.

Returns None on invalid hour, minute, second and/or microsecond.

[src]

Makes a new DateTime from the current date, hour, minute, second and nanosecond. The nanosecond part can exceed 1,000,000,000 in order to represent the leap second. The offset in the current date is preserved.

Panics on invalid hour, minute, second and/or nanosecond.

[src]

Makes a new DateTime from the current date, hour, minute, second and nanosecond. The nanosecond part can exceed 1,000,000,000 in order to represent the leap second. The offset in the current date is preserved.

Returns None on invalid hour, minute, second and/or nanosecond.

[src]

Makes a new Date for the next date.

Panics when self is the last representable date.

[src]

Makes a new Date for the next date.

Returns None when self is the last representable date.

[src]

Makes a new Date for the prior date.

Panics when self is the first representable date.

[src]

Makes a new Date for the prior date.

Returns None when self is the first representable date.

[src]

Retrieves an associated offset from UTC.

[src]

Retrieves an associated time zone.

[src]

Changes the associated time zone. This does not change the actual Date (but will change the string representation).

[src]

Adds given Duration to the current date.

Returns None when it will result in overflow.

[src]

Subtracts given Duration from the current date.

Returns None when it will result in overflow.

[src]

Subtracts another Date from the current date. Returns a Duration of integral numbers.

This does not overflow or underflow at all, as all possible output fits in the range of Duration.

[src]

Returns a view to the naive UTC date.

[src]

Returns a view to the naive local date.

This is technically same to naive_utc because the offset is restricted to never exceed one day, but provided for the consistency.

impl<Tz: TimeZone> Date<Tz> where
    Tz::Offset: Display
[src]

[src]

Formats the date with the specified formatting items.

[src]

Formats the date with the specified format string. See the format::strftime module on the supported escape sequences.
