Struct RegionIndexes

Source 
pub struct RegionIndexes {
    pub(crate) regions: HashMap<RegionId, BTreeSet<EntryId>>,
    pub(crate) latest_entry_id: EntryId,
}
Expand description

The RegionIndexes struct maintains indexes for a collection of regions. Each region is identified by a RegionId and maps to a set of EntryIds, representing the entries within that region. It also keeps track of the latest EntryId across all regions.
