Struct SplitPredicate 

pub struct SplitPredicate {
    pub sql_predicate: Predicate,
    pub remaining_predicate: Predicate,
}

Result of splitting a predicate for PostgreSQL execution.

“Pushdown” refers to moving predicate evaluation from the application layer down to the database layer. Some predicates can be translated to SQL and executed by PostgreSQL (pushdown), while others must be evaluated in Rust after fetching results (e.g., future features like Ref traversal).

Fields

sql_predicate: Predicate

Predicate that can be pushed down to PostgreSQL WHERE clause

remaining_predicate: Predicate

Predicate that must be evaluated in Rust after fetching (Predicate::True if nothing remains)
