Implementations

impl ExpressionOp

pub fn apply(self, left: &Value, right: &Value) -> Result<Value, Error>

Apply the operation to two values

Trait Implementations

impl Clone for ExpressionOp

fn clone(&self) -> ExpressionOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionOp

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

Formats the value using the given formatter.

impl PartialEq for ExpressionOp

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