Struct InSubquerySpec 

pub struct InSubquerySpec {
    pub outer_column: String,
    pub source_table: String,
    pub projection_column: String,
    pub predicate: Option<Box<BoolExpr>>,
}

v1.1: Specification for a scalar IN (SELECT ...) / NOT IN (SELECT ...) subquery.

Created by the linq! macro when parsing b.field.in_subquery(|p: Post| p.blog_id). Unlike SubquerySpec, this variant is not navigation-driven — the subquery projects a single column from an arbitrary table, and the outer column is compared against the projected values via the IN operator.

Fields

outer_column: String

The outer column being tested (e.g. "id" on the parent table).

source_table: String

The source table name for the inner SELECT (e.g. "posts").

projection_column: String

The projection column selected from the inner table (e.g. "blog_id").

predicate: Option<Box<BoolExpr>>

Optional predicate applied inside the subquery (e.g. WHERE published = ?).

Implementations
