Implementations

impl ScalarValue

pub fn get_datatype(&self) -> DataType

Getter for the DataType of the value

Trait Implementations

impl Clone for ScalarValue

fn clone(&self) -> ScalarValue

Returns a copy 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<ScalarValue> for ScalarValue

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

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

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

This method tests for !=.
