Struct polars_arrow::scalar::UnionScalar

pub struct UnionScalar { /* private fields */ }

A single entry of a crate::array::UnionArray.

Implementations

impl UnionScalar

pub fn new(data_type: ArrowDataType, type_: i8, value: Box<dyn Scalar>) -> Self

Returns a new UnionScalar

pub fn value(&self) -> &Box<dyn Scalar>

Returns the inner value

pub fn type_(&self) -> i8

Returns the type of the union scalar

Trait Implementations

impl Clone for UnionScalar

fn clone(&self) -> UnionScalar

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnionScalar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UnionScalar

fn eq(&self, other: &UnionScalar) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Scalar for UnionScalar

fn as_any(&self) -> &dyn Any

convert itself to

fn is_valid(&self) -> bool

whether it is valid

fn data_type(&self) -> &ArrowDataType

the logical type.
