Struct sqlx::types::chrono::DateTime [−][src]
pub struct DateTime<Tz> where
Tz: TimeZone, { /* fields omitted */ }
Expand description
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]
impl<Tz> DateTime<Tz> where
Tz: TimeZone,
[src]pub fn from_utc(
datetime: NaiveDateTime,
offset: <Tz as TimeZone>::Offset
) -> DateTime<Tz>
[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 time(&self) -> NaiveTime
[src]
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]
pub fn timestamp(&self) -> i64
[src]Returns the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka āUNIX timestampā).
pub fn timestamp_millis(&self) -> i64
[src]
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, Iām 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]
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, Iām 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]
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]
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]
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 with_timezone<Tz2>(&self, tz: &Tz2) -> DateTime<Tz2> where
Tz2: TimeZone,
[src]
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]
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]
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]
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]
pub fn naive_utc(&self) -> NaiveDateTime
[src]Returns a view to the naive UTC datetime.
pub fn naive_local(&self) -> NaiveDateTime
[src]
pub fn naive_local(&self) -> NaiveDateTime
[src]Returns a view to the naive local datetime.
impl DateTime<FixedOffset>
[src]
impl DateTime<FixedOffset>
[src]pub fn parse_from_rfc2822(s: &str) -> Result<DateTime<FixedOffset>, ParseError>
[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]
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 isnāt this named parse_from_iso8601
? Thatās 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]
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)));

[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]
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]
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 āZā, as per
Fixed::TimezoneOffsetColonZ.
If passed use_z
false, use
Fixed::TimezoneOffsetColon.
