Implementations

impl<T> FilterExpression<T>

pub fn exists(op: Operand<T>) -> Self

Trait Implementations

impl<T: Clone> Clone for FilterExpression<T>

fn clone(&self) -> FilterExpression<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for FilterExpression<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for FilterExpression<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for FilterExpression<T>

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