Implementations

impl ScalarValue

pub fn data_type(&self) -> DataType

Get the Arrow DataType for this value.

pub fn from_array(array: &ArrayRef, idx: usize) -> DbxResult<Self>

Extract a value from an Arrow array at the given index.

Trait Implementations

impl Clone for ScalarValue

fn clone(&self) -> ScalarValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarValue

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

Formats the value using the given formatter.

impl PartialEq for ScalarValue

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

Tests for self and other values to be equal, and is used by ==.

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

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