Implementations

impl DatetimeChunked

pub fn as_datetime_iter(
    &self

Available on crate features temporal or dtype-datetime or dtype-date only.

pub fn time_unit(&self) -> TimeUnit

Available on crate features temporal or dtype-datetime or dtype-date only.

pub fn time_zone(&self) -> &Option<TimeZone>

Available on crate features temporal or dtype-datetime or dtype-date only.

pub fn apply_on_tz_corrected<F>(&self, func: F) -> PolarsResult<DatetimeChunked>where
    F: FnMut(DatetimeChunked) -> PolarsResult<DatetimeChunked>,

Available on crate features temporal or dtype-datetime or dtype-date only.

pub fn cast_time_zone(&self, tz: &str) -> PolarsResult<DatetimeChunked>

Available on (crate features temporal or dtype-datetime or dtype-date) and crate feature timezones only.

pub fn strftime(&self, fmt: &str) -> Utf8Chunked

Available on crate features temporal or dtype-datetime or dtype-date only.

Format Datetime with a fmt rule. See chrono strftime/strptime.

pub fn from_naive_datetime<I: IntoIterator<Item = NaiveDateTime>>(
    name: &str,
    v: I,
    tu: TimeUnit
) -> Self

Available on crate features temporal or dtype-datetime or dtype-date only.

Construct a new DatetimeChunked from an iterator over NaiveDateTime.

pub fn from_naive_datetime_options<I: IntoIterator<Item = Option<NaiveDateTime>>>(
    name: &str,
    v: I,
    tu: TimeUnit
) -> Self

Available on crate features temporal or dtype-datetime or dtype-date only.

pub fn cast_time_unit(&self, tu: TimeUnit) -> Self

Available on crate features temporal or dtype-datetime or dtype-date only.

Change the underlying TimeUnit. And update the data accordingly.

pub fn set_time_unit(&mut self, tu: TimeUnit)

Available on crate features temporal or dtype-datetime or dtype-date only.

Change the underlying TimeUnit. This does not modify the data.

pub fn set_time_zone(&mut self, tz: Option<TimeZone>)

Available on crate features temporal or dtype-datetime or dtype-date only.

Change the underlying TimeZone. This does not modify the data.

pub fn with_time_zone(self, tz: Option<TimeZone>) -> Self

Available on crate features temporal or dtype-datetime or dtype-date only.
