Implementations

impl QDateTime

pub fn add_months(&self, nmonths: i32) -> QDateTime

Returns a QDateTime object containing a datetime nmonths months later than the datetime of this object (or earlier if nmonths is negative).

impl QDateTime

pub fn add_years(&self, nyears: i32) -> QDateTime

Returns a QDateTime object containing a datetime nyears years later than the datetime of this object (or earlier if nyears is negative).

impl QDateTime

pub fn date(&self) -> QDate

Returns the date part of the datetime.

impl QDateTime

pub fn is_daylight_time(&self) -> bool

Returns if this datetime falls in Daylight-Saving Time.

impl QDateTime

pub fn is_null(&self) -> bool

Returns true if both the date and the time are null; otherwise returns false. A null datetime is invalid.

impl QDateTime

pub fn is_valid(&self) -> bool

Returns true if both the date and the time are valid and they are valid in the current Qt::TimeSpec, otherwise returns false.

impl QDateTime

pub fn offset_from_utc(&self) -> i32

Returns this date-time’s Offset From UTC in seconds.

impl QDateTime

pub fn set_offset_from_utc(&mut self, offset_seconds: i32)

Sets the timeSpec() to Qt::OffsetFromUTC and the offset to offsetSeconds.

Note this method is only available with Qt < 6.8

impl QDateTime

pub fn set_time_spec(&mut self, spec: TimeSpec)

Sets the time specification used in this datetime to spec. The datetime will refer to a different point in time.

Note this method is only available with Qt < 6.8

impl QDateTime

pub fn time(&self) -> QTime

Returns the time part of the datetime.

impl QDateTime

pub fn time_spec(&self) -> TimeSpec

Returns the time specification of the datetime.

impl QDateTime

pub fn time_zone_abbreviation(&self) -> QString

Returns the Time Zone Abbreviation for this datetime.

impl QDateTime

pub fn to_local_time(&self) -> QDateTime

Returns a datetime containing the date and time information in this datetime, but specified using the Qt::LocalTime definition.

pub fn to_offset_from_utc(&self, offset_seconds: i32) -> QDateTime

Returns a copy of this datetime converted to a spec of Qt::OffsetFromUTC with the given offsetSeconds.

impl QDateTime

pub fn to_time_spec(&self, spec: TimeSpec) -> QDateTime

Returns a copy of this datetime converted to the given time spec.

Note this method is only available with Qt < 6.8

Returns a QDateTime object containing a datetime ndays days later than the datetime of this object (or earlier if ndays is negative).

pub fn add_msecs(&self, msecs: i64) -> Self

Returns a QDateTime object containing a datetime msecs milliseconds later than the datetime of this object (or earlier if msecs is negative).

pub fn add_secs(&self, secs: i64) -> Self

Returns a QDateTime object containing a datetime s seconds later than the datetime of this object (or earlier if s is negative).

pub fn current_date_time() -> Self

Returns the current datetime, as reported by the system clock, in the local time zone.

pub fn current_date_time_utc() -> Self

Returns the current datetime, as reported by the system clock, in UTC.

pub fn current_msecs_since_epoch() -> i64

Returns the number of milliseconds since 1970-01-01T00:00:00 Universal Coordinated Time. This number is like the POSIX time_t variable, but expressed in milliseconds instead.

pub fn current_secs_since_epoch() -> i64

Returns the number of seconds since 1970-01-01T00:00:00 Universal Coordinated Time.

pub fn days_to(&self, other: &Self) -> i64

Returns the number of days from this datetime to the other datetime. The number of days is counted as the number of times midnight is reached between this datetime to the other datetime. This means that a 10 minute difference from 23:55 to 0:05 the next day counts as one day.

pub fn from_date_and_time_time_zone( date: &QDate, time: &QTime, time_zone: &QTimeZone, ) -> Self

Construct a Rust QDateTime from a given QDate, QTime, and QTimeZone

pub fn from_date_and_time_time_spec( date: &QDate, time: &QTime, time_spec: TimeSpec, offset_seconds: i32, ) -> Self

Construct a Rust QDateTime from a given QDate, QTime, Qt::TimeSpec, and offset

Note this method is only available with Qt < 6.8

pub fn from_msecs_since_epoch(msecs: i64, time_zone: &QTimeZone) -> Self

Returns a datetime whose date and time are the number of milliseconds msecs that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC) and with the given timeZone.

pub fn from_secs_since_epoch(secs: i64, time_zone: &QTimeZone) -> Self

Returns a datetime whose date and time are the number of seconds secs that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC) and converted to the given spec.

pub fn msecs_to(&self, other: &Self) -> i64

Returns the number of milliseconds from this datetime to the other datetime. If the other datetime is earlier than this datetime, the value returned is negative.

pub fn secs_to(&self, other: &Self) -> i64

Returns the number of seconds from this datetime to the other datetime. If the other datetime is earlier than this datetime, the value returned is negative.

pub fn set_date(&mut self, date: QDate)

Sets the date part of this datetime to date. If no time is set yet, it is set to midnight. If date is invalid, this QDateTime becomes invalid.

pub fn set_msecs_since_epoch(&mut self, msecs: i64)

Sets the date and time given the number of milliseconds msecs that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC). On systems that do not support time zones this function will behave as if local time were Qt::UTC.

pub fn set_secs_since_epoch(&mut self, secs: i64)

Sets the date and time given the number of seconds secs that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC). On systems that do not support time zones this function will behave as if local time were Qt::UTC.

pub fn set_time(&mut self, time: QTime)

Sets the time part of this datetime to time. If time is not valid, this function sets it to midnight. Therefore, it’s possible to clear any set time in a QDateTime by setting it to a default QTime.

pub fn time_zone(&self) -> UniquePtr<QTimeZone>

Returns the time zone of the datetime.

pub fn to_msecs_since_epoch(&self) -> i64

Returns the datetime as the number of milliseconds that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC).

pub fn to_secs_since_epoch(&self) -> i64

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt::UTC).
