Struct WANDStats 

pub struct WANDStats {
    pub scored: u64,
    pub total_candidates: u64,
    pub cursor_advances: u64,
}

Stats collected during a top-k pass; tests use these to assert the exit-criterion skip rates from the master plan.

Skip rate semantics are 1 - scored / total_candidates. The materialized path reports the exact union of posting-list document ids. The score-cursor path deliberately avoids a complete pre-scan and reports the sum of term document frequencies, a safe upper bound on that union. scored counts documents for which the complete query score was evaluated; cursor_advances counts pivot-driven skips and is informational only.

Fields

scored: u64

total_candidates: u64

cursor_advances: u64
