[][src]Struct sentry_core::types::DateTime

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

ISO 8601 combined date and time with time zone.

There are some constructors implemented here (the from_* methods), but the general-purpose constructors are all via the methods on the TimeZone implementations.

Implementations

impl<Tz> DateTime<Tz> where
    Tz: TimeZone
[src]

pub fn from_utc(
    datetime: NaiveDateTime,
    offset: <Tz as TimeZone>::Offset
) -> DateTime<Tz>
[src]

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

Example

use chrono::{DateTime, TimeZone, NaiveDateTime, Utc};

let dt = DateTime::<Utc>::from_utc(NaiveDateTime::from_timestamp(61, 0), Utc);
assert_eq!(Utc.timestamp(61, 0), dt);

pub fn date(&self) -> Date<Tz>[src]

Retrieves a date component.

pub fn time(&self) -> NaiveTime[src]

Retrieves a time component. Unlike date, this is not associated to the time zone.

pub fn timestamp(&self) -> i64[src]

Returns the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

pub fn timestamp_millis(&self) -> i64[src]

Returns the number of non-leap-milliseconds since January 1, 1970 UTC

Note that this does reduce the number of years that can be represented from ~584 Billion to ~584 Million. (If this is a problem, please file an issue to let me know what domain needs millisecond precision over billions of years, I'm curious.)

Example

use chrono::Utc;
use chrono::TimeZone;

let dt = Utc.ymd(1970, 1, 1).and_hms_milli(0, 0, 1, 444);
assert_eq!(dt.timestamp_millis(), 1_444);

let dt = Utc.ymd(2001, 9, 9).and_hms_milli(1, 46, 40, 555);
assert_eq!(dt.timestamp_millis(), 1_000_000_000_555);

pub fn timestamp_nanos(&self) -> i64[src]

Returns the number of non-leap-nanoseconds since January 1, 1970 UTC

Note that this does reduce the number of years that can be represented from ~584 Billion to ~584. (If this is a problem, please file an issue to let me know what domain needs nanosecond precision over millennia, I'm curious.)

Example

use chrono::Utc;
use chrono::TimeZone;

let dt = Utc.ymd(1970, 1, 1).and_hms_nano(0, 0, 1, 444);
assert_eq!(dt.timestamp_nanos(), 1_000_000_444);

let dt = Utc.ymd(2001, 9, 9).and_hms_nano(1, 46, 40, 555);
assert_eq!(dt.timestamp_nanos(), 1_000_000_000_000_000_555);

pub fn timestamp_subsec_millis(&self) -> u32[src]

Returns the number of milliseconds since the last second boundary

warning: in event of a leap second, this may exceed 999

note: this is not the number of milliseconds since January 1, 1970 0:00:00 UTC

pub fn timestamp_subsec_micros(&self) -> u32[src]

Returns the number of microseconds since the last second boundary

warning: in event of a leap second, this may exceed 999_999

note: this is not the number of microseconds since January 1, 1970 0:00:00 UTC

pub fn timestamp_subsec_nanos(&self) -> u32[src]

Returns the number of nanoseconds since the last second boundary

warning: in event of a leap second, this may exceed 999_999_999

note: this is not the number of nanoseconds since January 1, 1970 0:00:00 UTC

pub fn offset(&self) -> &<Tz as TimeZone>::Offset[src]

Retrieves an associated offset from UTC.

pub fn timezone(&self) -> Tz[src]

Retrieves an associated time zone.

pub fn with_timezone<Tz2>(&self, tz: &Tz2) -> DateTime<Tz2> where
    Tz2: TimeZone
[src]

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

pub fn checked_add_signed(self, rhs: Duration) -> Option<DateTime<Tz>>[src]

Adds given Duration to the current date and time.

Returns None when it will result in overflow.

pub fn checked_sub_signed(self, rhs: Duration) -> Option<DateTime<Tz>>[src]

Subtracts given Duration from the current date and time.

Returns None when it will result in overflow.

pub fn signed_duration_since<Tz2>(self, rhs: DateTime<Tz2>) -> Duration where
    Tz2: TimeZone
[src]

Subtracts another DateTime from the current date and time. This does not overflow or underflow at all.

pub fn naive_utc(&self) -> NaiveDateTime[src]

Returns a view to the naive UTC datetime.

pub fn naive_local(&self) -> NaiveDateTime[src]

Returns a view to the naive local datetime.

impl DateTime<FixedOffset>[src]

pub fn parse_from_rfc2822(s: &str) -> Result<DateTime<FixedOffset>, ParseError>[src]

Parses an RFC 2822 date and time string such as Tue, 1 Jul 2003 10:52:37 +0200, then returns a new DateTime with a parsed FixedOffset.

RFC 2822 is the internet message standard that specifices the representation of times in HTTP and email headers.

assert_eq!(
    DateTime::parse_from_rfc2822("Wed, 18 Feb 2015 23:16:09 GMT").unwrap(),
    FixedOffset::east(0).ymd(2015, 2, 18).and_hms(23, 16, 9)
);

pub fn parse_from_rfc3339(s: &str) -> Result<DateTime<FixedOffset>, ParseError>[src]

Parses an RFC 3339 and ISO 8601 date and time string such as 1996-12-19T16:39:57-08:00, then returns a new DateTime with a parsed FixedOffset.

Why isn't this named parse_from_iso8601? That's because ISO 8601 allows some freedom over the syntax and RFC 3339 exercises that freedom to rigidly define a fixed format.

pub fn parse_from_str(
    s: &str,
    fmt: &str
) -> Result<DateTime<FixedOffset>, ParseError>
[src]

Parses a string with the specified format string and returns a new DateTime with a parsed FixedOffset. See the format::strftime module on the supported escape sequences.

See also Offset::datetime_from_str which gives a local DateTime on specific time zone.

Note that this method requires a timezone in the string. See NaiveDateTime::parse_from_str for a version that does not require a timezone in the to-be-parsed str.

Example

use chrono::{DateTime, FixedOffset, TimeZone};

let dt = DateTime::parse_from_str(
    "1983 Apr 13 12:09:14.274 +0000", "%Y %b %d %H:%M:%S%.3f %z");
assert_eq!(dt, Ok(FixedOffset::east(0).ymd(1983, 4, 13).and_hms_milli(12, 9, 14, 274)));

impl<Tz> DateTime<Tz> where
    Tz: TimeZone,
    <Tz as TimeZone>::Offset: Display
[src]

pub fn to_rfc2822(&self) -> String[src]

Returns an RFC 2822 date and time string such as Tue, 1 Jul 2003 10:52:37 +0200.

pub fn to_rfc3339(&self) -> String[src]

Returns an RFC 3339 and ISO 8601 date and time string such as 1996-12-19T16:39:57-08:00.

pub fn to_rfc3339_opts(&self, secform: SecondsFormat, use_z: bool) -> String[src]

Return an RFC 3339 and ISO 8601 date and time string with subseconds formatted as per a SecondsFormat. If passed use_z true and the timezone is UTC (offset 0), use 'Z', as per Fixed::TimezoneOffsetColonZ. If passed use_z false, use Fixed::TimezoneOffsetColon.

Examples

let dt = Utc.ymd(2018, 1, 26).and_hms_micro(18, 30, 9, 453_829);
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Millis, false),
           "2018-01-26T18:30:09.453+00:00");
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Millis, true),
           "2018-01-26T18:30:09.453Z");
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Secs, true),
           "2018-01-26T18:30:09Z");

let pst = FixedOffset::east(8 * 60 * 60);
let dt = pst.ymd(2018, 1, 26).and_hms_micro(10, 30, 9, 453_829);
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Secs, true),
           "2018-01-26T10:30:09+08:00");

pub fn format_with_items<'a, I, B>(&self, items: I) -> DelayedFormat<I> where
    B: Borrow<Item<'a>>,
    I: Iterator<Item = B> + Clone
[src]

Formats the combined date and time with the specified formatting items.

pub fn format(&self, fmt: &'a str) -> DelayedFormat<StrftimeItems<'a>>[src]

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