Struct CorrelatedSubqueryCondition 

pub struct CorrelatedSubqueryCondition {
    pub related: CorrelatedSubquery,
    pub op: ExistsOp,
    pub flip: Option<bool>,
    pub scalar: Option<bool>,
    pub plan_id: Option<u32>,
}

A (NOT) EXISTS condition (CorrelatedSubqueryCondition, ast.ts:324-331).

Fields

related: CorrelatedSubquery

The subquery + how it correlates to the parent.

op: ExistsOp

EXISTS | NOT EXISTS.

flip: Option<bool>

Flipped-join routing flag (read by the builder / planner). Deferred path.

scalar: Option<bool>

Scalar-subquery flag. Deferred path.

plan_id: Option<u32>

Build-time planner annotation — not wire data (#[serde(skip)]), set by the planner (deferred), and always None today. Once the planner sets it, it must be excluded from PartialEq/canonical ordering (spec 02 §4.4); it is None-only now, so the derived PartialEq is correct in the interim.

Trait Implementations

impl Clone for CorrelatedSubqueryCondition

fn clone(&self) -> CorrelatedSubqueryCondition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CorrelatedSubqueryCondition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CorrelatedSubqueryCondition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CorrelatedSubqueryCondition

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

impl Serialize for CorrelatedSubqueryCondition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
