impl<'a> From<&'a String> for Scalar

fn from(s: &String) -> Scalar

Converts to this type from the input type.

impl From<&'static str> for Scalar

fn from(s: &'static str) -> Scalar

Converts to this type from the input type.

impl From<DateTime<FixedOffset>> for Scalar

fn from(s: DateTime<FixedOffset>) -> Scalar

Converts to this type from the input type.

impl From<String> for Scalar

fn from(s: String) -> Scalar

Converts to this type from the input type.

impl From<bool> for Scalar

impl PartialEq<Scalar> for Scalar

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
