async fn reverse_bitmap(
map: &Arc<Map>,
words: usize,
progress: &Progress,
) -> Result<(Vec<u64>, u64, u64)>Expand description
Streams a reverse map into its keyset bitmap, its row count, and its count of keys that are not an 8-byte short id.
The rows are counted here rather than in the loser pass, which a clean family skips.
