Trait Implementations

impl Debug for ScalarValue

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

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 PartialEq for ScalarValue

fn eq(&self, __arg_0: &ScalarValue) -> bool

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

fn ne(&self, __arg_0: &ScalarValue) -> bool

This method tests for !=.

impl PartialOrd for ScalarValue

fn partial_cmp(&self, other: &ScalarValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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

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.
