Struct Hit 

pub(crate) struct Hit {
    ts: i64,
    pub(crate) block: usize,
    pub(crate) row: u32,
}

One matching record, kept only long enough to sort and materialize.

Holds a block index and a row number, not the row’s data: a query over a wide window can match millions of rows and keep a hundred, and copying the other 999,900 out of the mapping in order to discard them is the easiest way to make a columnar engine slow.
