Type Definition polars_core::datatypes::DurationChunked

pub type DurationChunked = Logical<DurationType, Int64Type>;

Available on crate feature dtype-duration only.

Implementations

impl DurationChunked

pub fn time_unit(&self) -> TimeUnit

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 from_duration<I: IntoIterator<Item = ChronoDuration>>(
    name: &str,
    v: I,
    tu: TimeUnit
) -> Self

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

Construct a new DurationChunked from an iterator over ChronoDuration.

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

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

Construct a new DurationChunked from an iterator over optional ChronoDuration.
