Struct PreparedPredicate 

pub struct PreparedPredicate<'a> {
    pub storage: Option<Box<dyn StorageExpression>>,
    pub residual: Option<Expression>,
    /* private fields */
}

One prepared predicate shared by index selection and scan construction. effective preserves the statement-level predicate for feedback and cache identity; residual is the exact executor-side remainder after pushdown.

Fields

storage: Option<Box<dyn StorageExpression>>

residual: Option<Expression>
