Struct lance_table::rowids::RowIdIndex

pub struct RowIdIndex(/* private fields */);

An index of row ids

This index is used to map row ids to their corresponding addresses. These addresses correspond to physical positions in the dataset. See RowAddress.

This structure only contains rows that physically exist. However, it may map to addresses that have been tombstoned. A separate tombstone index is used to track tombstoned rows.

Implementations

impl RowIdIndex

pub fn new(fragment_indices: &[(u32, RowIdSequence)]) -> Result<Self>

Create a new index from a list of fragment ids and their corresponding row id sequences.

pub fn get(&self, row_id: u64) -> Option<RowAddress>

Get the address for a given row id.

Will return None if the row id does not exist in the index.
