Struct raftstore::store::RegionIterator[−][src]

pub struct RegionIterator<S: Snapshot> {
    iter: <S as Iterable>::Iterator,
    region: Arc<Region>,
}
[−]

RegionIterator wrap a rocksdb iterator and only allow it to iterate in the region. It behaves as if underlying db only contains one region.

Fields

iter: <S as Iterable>::Iteratorregion: Arc<Region>
