Trait RuleRowValues 

pub trait RuleRowValues {
    // Required methods
    fn old_row(&self) -> Option<&Document>;
    fn new_row(&self) -> Option<&Document>;
    fn old_doc_id(&self) -> Option<DocId>;
    fn new_doc_id(&self) -> Option<DocId>;
}

Logical OLD/NEW values used by rule action binding. Physical origins and source contexts stay in the executor.

Required Methods

fn old_row(&self) -> Option<&Document>

fn new_row(&self) -> Option<&Document>

fn old_doc_id(&self) -> Option<DocId>

fn new_doc_id(&self) -> Option<DocId>
