Required Methods§

fn get_idlayer(&mut self) -> &mut Self::IdlLayerType

source

fn get_ruv(&mut self) -> &mut Self::RuvType

source

fn get_idxmeta_ref(&self) -> &IdxMeta

Provided Methods§

source

fn filter2idl( &mut self, filt: &FilterResolved, thres: usize, ) -> Result<(IdList, FilterPlan), OperationError>

Recursively apply a filter, transforming into IdList’s on the way. This builds a query execution log, so that it can be examined how an operation proceeded.

source

fn filter2idl_sub( &mut self, attr: &Attribute, sub_idx_key: String, ) -> Result<(IdList, FilterPlan), OperationError>

source

fn search( &mut self, erl: &Limits, filt: &Filter<FilterValidResolved>, ) -> Result<Vec<Arc<EntrySealedCommitted>>, OperationError>

source

fn exists( &mut self, erl: &Limits, filt: &Filter<FilterValidResolved>, ) -> Result<bool, OperationError>

Given a filter, assert some condition exists. Basically, this is a specialised case of search, where we don’t need to load any candidates if they match. This is heavily used in uuid refint and attr uniqueness.
