Implementations

impl IndexState

pub fn apply(&mut self, entry: IndexEntry) -> Result<(), DbError>

pub fn unique_lookup( &self, collection_id: u32, index_name: &str, index_key: &[u8], ) -> Option<&[u8]>

pub fn non_unique_lookup( &self, collection_id: u32, index_name: &str, index_key: &[u8], ) -> Option<Vec<Vec<u8>>>

pub fn non_unique_range_lookup( &self, collection_id: u32, index_name: &str, lo: Option<&ScalarValue>, lo_inclusive: bool, hi: Option<&ScalarValue>, hi_inclusive: bool, ) -> Vec<Vec<u8>>

Collect PK keys for all index entries whose key falls in [lo, hi] (per scalar_partial_cmp).

pub fn unique_range_lookup( &self, collection_id: u32, index_name: &str, lo: Option<&ScalarValue>, lo_inclusive: bool, hi: Option<&ScalarValue>, hi_inclusive: bool, ) -> Vec<Vec<u8>>

Collect PK keys for unique index entries whose key falls in [lo, hi].
