Implementations

impl Logical<DatetimeType, Int64Type>

pub fn as_datetime_iter(&self) -> impl TrustedLen

pub fn time_unit(&self) -> TimeUnit

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

pub fn to_string( &self, format: &str, ) -> Result<ChunkedArray<StringType>, PolarsError>

Convert from Datetime into String with the given format. See chrono strftime/strptime.

pub fn strftime( &self, format: &str, ) -> Result<ChunkedArray<StringType>, PolarsError>

Convert from Datetime into String with the given format. See chrono strftime/strptime.

Alias for to_string.

pub fn from_naive_datetime<I>( name: PlSmallStr, v: I, tu: TimeUnit, ) -> Logical<DatetimeType, Int64Type>

where I: IntoIterator<Item = NaiveDateTime>,

Construct a new DatetimeChunked from an iterator over NaiveDateTime.

pub fn from_naive_datetime_options<I>( name: PlSmallStr, v: I, tu: TimeUnit, ) -> Logical<DatetimeType, Int64Type>

where I: IntoIterator<Item = Option<NaiveDateTime>>,

pub fn cast_time_unit(&self, tu: TimeUnit) -> Logical<DatetimeType, Int64Type>

Change the underlying TimeUnit. And update the data accordingly.

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

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

pub fn set_time_zone( &mut self, time_zone: PlSmallStr, ) -> Result<(), PolarsError>

Change the underlying TimeZone. This does not modify the data. This does not validate the time zone - it’s up to the caller to verify that it’s already been validated.

pub fn set_time_unit_and_time_zone( &mut self, time_unit: TimeUnit, time_zone: PlSmallStr, ) -> Result<(), PolarsError>

Change the underlying TimeUnit and TimeZone. This does not modify the data. This does not validate the time zone - it’s up to the caller to verify that it’s already been validated.
