Trait Implementations

impl Clone for FillNull

fn clone(&self) -> FillNull

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FillNull

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

Formats the value using the given formatter.

impl From<&str> for FillNull

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<FillNullStrategy> for FillNull

fn from(strategy: FillNullStrategy) -> Self

Converts to this type from the input type.

impl From<Scalar> for FillNull

fn from(value: Scalar) -> Self

Converts to this type from the input type.

impl From<String> for FillNull

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<bool> for FillNull

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for FillNull

fn from(value: f64) -> Self

impl From<i64> for FillNull

fn from(value: i64) -> Self

impl PartialEq for FillNull

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

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

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