pub fn ensure_fts_index(conn: &Connection) -> Result<(), Error>Expand description
Ensures the symbols_fts FTS5 virtual table and synchronization triggers exist in the SQLite
database, and that it holds every symbol except locals and parameters. An index built under an
earlier rule, or one left without content, is repopulated once.
julie may write a local before its enclosing function, so the insert trigger also drops any
same-file variable that became local when its parent arrived.
