}

Variants

Atom(Operand, FilterSign, Operand)

a single expression like a > 2

And(Box<FilterExpression>, Box<FilterExpression>)

and with &&

or with ||

Not(Box<FilterExpression>)

not with !

Implementations

impl FilterExpression

pub fn exists(op: Operand) -> Self

Trait Implementations

impl Clone for FilterExpression

fn clone(&self) -> FilterExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilterExpression

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

Formats the value using the given formatter.

impl PartialEq for FilterExpression

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