Implementations

impl<T> PrimitiveArray<T>

where T: NativeType,

pub fn try_new( dtype: ArrowDataType, values: Buffer<T>, validity: Option<Bitmap>, ) -> Result<PrimitiveArray<T>, PolarsError>

The canonical method to create a PrimitiveArray out of its internal components.

Implementation

This function is O(1).

Errors

This function errors iff:

• The validity is not None and its length is different from values’s length
• The dtype’s PhysicalType is not equal to [PhysicalType::Primitive(T::PRIMITIVE)]

pub unsafe fn new_unchecked( dtype: ArrowDataType, values: Buffer<T>, validity: Option<Bitmap>, ) -> PrimitiveArray<T>

Safety

Doesn’t check invariants

pub fn to(self, dtype: ArrowDataType) -> PrimitiveArray<T>

Returns a new PrimitiveArray with a different logical type.

This function is useful to assign a different ArrowDataType to the array. Used to change the arrays’ logical type (see example).

Example

use polars_arrow::array::Int32Array;
use polars_arrow::datatypes::ArrowDataType;

let array = Int32Array::from(&[Some(1), None, Some(2)]).to(ArrowDataType::Date32);
assert_eq!(
   format!("{:?}", array),
   "Date32[1970-01-02, None, 1970-01-03]"
);

Panics

Panics iff the dtype’s PhysicalType is not equal to [PhysicalType::Primitive(T::PRIMITIVE)]

pub fn from_vec(values: Vec<T>) -> PrimitiveArray<T>

pub fn into_mut(self) -> Either<PrimitiveArray<T>, MutablePrimitiveArray<T>>

Try to convert this PrimitiveArray to a MutablePrimitiveArray via copy-on-write semantics.

A PrimitiveArray is backed by a Buffer and Bitmap which are essentially Arc<Vec<_>>. This function returns a MutablePrimitiveArray (via std::sync::Arc::get_mut) iff both values and validity have not been cloned / are unique references to their underlying vectors.

This function is primarily used to reuse memory regions.

where I: TrustedLen<Item = Option<T>>,

Creates a PrimitiveArray from a TrustedLen of optional values.

Safety

pub fn new( dtype: ArrowDataType, values: Buffer<T>, validity: Option<Bitmap>, ) -> PrimitiveArray<T>

Alias for Self::try_new(..).unwrap().

Panics
