Implementations

impl NullScalar

pub fn new() -> Self

A new NullScalar

Trait Implementations

impl Clone for NullScalar

fn clone(&self) -> NullScalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NullScalar

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

Formats the value using the given formatter.

impl Default for NullScalar

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for NullScalar

fn eq(&self, other: &NullScalar) -> 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 NullScalar

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.

impl Eq for NullScalar

impl StructuralPartialEq for NullScalar
