Struct polars_arrow::scalar::FixedSizeListScalar

pub struct FixedSizeListScalar { /* private fields */ }

The scalar equivalent of FixedSizeListArray. Like FixedSizeListArray, this struct holds a dynamically-typed Array. The only difference is that this has only one element.

Implementations

impl FixedSizeListScalar

pub fn new(data_type: ArrowDataType, values: Option<Box<dyn Array>>) -> Self

returns a new FixedSizeListScalar

Panics

iff

• the data_type is not FixedSizeList
• the child of the data_type is not equal to the values
• the size of child array is not equal

pub fn values(&self) -> Option<&Box<dyn Array>>

The values of the FixedSizeListScalar

Trait Implementations

impl Clone for FixedSizeListScalar

fn clone(&self) -> FixedSizeListScalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FixedSizeListScalar

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

Formats the value using the given formatter.

impl PartialEq for FixedSizeListScalar

fn eq(&self, other: &Self) -> 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 FixedSizeListScalar

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.
