Struct arrow2::scalar::StructScalar

pub struct StructScalar { /* private fields */ }

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

Implementations

impl StructScalar

pub fn new(data_type: DataType, values: Option<Vec<Box<dyn Scalar>>>) -> Self

Returns a new StructScalar

pub fn values(&self) -> &[Box<dyn Scalar>]

Returns the values irrespectively of the validity.

Trait Implementations

impl Clone for StructScalar

fn clone(&self) -> StructScalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StructScalar

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

Formats the value using the given formatter.

impl PartialEq for StructScalar

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 StructScalar

fn as_any(&self) -> &dyn Any

convert itself to

fn is_valid(&self) -> bool

whether it is valid

fn data_type(&self) -> &DataType

the logical type.
