Struct CorrelatedSubquery 

pub struct CorrelatedSubquery {
    pub correlation: Correlation,
    pub subquery: Box<Ast>,
    pub system: Option<System>,
}

A child query joined to its parent by a key Correlation (CorrelatedSubquery, ast.ts:250-265). Used both as a materialized relationship (Ast::related) and inside a CorrelatedSubqueryCondition.

Fields

correlation: Correlation

How the child relates to the parent (the join key pair).

subquery: Box<Ast>

The child query. Boxed to break the Ast→CorrelatedSubquery→Ast cycle.

system: Option<System>

Origin: 'client' | 'permissions' | 'test'. Wire-optional; the builder defaults absent ⇒ client.

Trait Implementations

impl Clone for CorrelatedSubquery

fn clone(&self) -> CorrelatedSubquery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CorrelatedSubquery

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CorrelatedSubquery

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CorrelatedSubquery

fn eq(&self, other: &CorrelatedSubquery) -> 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 CorrelatedSubquery

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
