See load_extension_enable for an example. enable_load_extension (enabled) ¶ This routine allows/disallows the SQLite engine to load SQLite extensions from shared libraries. Extension loading must be enabled using sqlite3_enable_load_extension() or sqlite3_db_config(db,SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION,1,NULL) prior to calling this API, otherwise an error will be returned. Fast. Use sqlite3_db_config(db,SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION,..) prior to calling this API, Call the sqlite3_enable_load_extension() routine with onoff==1 THE call that makes the difference between crash and no crash is sqlite3_open. pub fn load_extension
