Struct Q42RangeVolumeSetNestedLoopJoinState 

Source 
pub struct Q42RangeVolumeSetNestedLoopJoinState {
    pub left_scan: Q42RangeVolumeSetSparqlCursor,
    pub right_scan: Q42RangeVolumeSetSparqlCursor,
    pub left_count: usize,
    pub left_index: usize,
    pub left_exhausted: bool,
    pub right_active: bool,
}
Expand description

Resumable state for the logical-volume equivalent of Q42RangeNestedLoopJoinState. The cursors include manifest child positions, so a join never has to re-open or materialise a volume set.
