Bound predicate expression after binding to a schema.

Variants

AlwaysTrue

An expression always evaluates to true.

AlwaysFalse

An expression always evaluates to false.

And(LogicalExpression<BoundPredicate, 2>)

An expression combined by AND, for example, a > 10 AND b < 20.

Or(LogicalExpression<BoundPredicate, 2>)

An expression combined by OR, for example, a > 10 OR b < 20.

Not(LogicalExpression<BoundPredicate, 1>)

An expression combined by NOT, for example, NOT (a > 10).

Unary(UnaryExpression<BoundReference>)

Unary expression, for example, a IS NULL.

Binary(BinaryExpression<BoundReference>)

Binary expression, for example, a > 10.

Set(SetExpression<BoundReference>)

Set predicates, for example, a IN (1, 2, 3).

Trait Implementations

impl Clone for BoundPredicate

fn clone(&self) -> BoundPredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BoundPredicate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BoundPredicate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BoundPredicate

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

Formats the value using the given formatter.

impl PartialEq for BoundPredicate

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

impl Serialize for BoundPredicate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
