Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl From<&str> for Scalar

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<()> for Scalar

fn from(_: ()) -> 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 Scalar

fn from(v: String) -> Self

Converts to this type from the input type.

impl From<bool> for Scalar

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Scalar

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Scalar

fn from(v: i64) -> Self

Converts to this type from the input type.

impl PartialEq for Scalar

fn eq(&self, other: &Scalar) -> 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.
