Expand description
FromProof + Fetch for [DocumentCount] — the single-row
aggregate count view of the unified getDocuments endpoint.
Callers build a DocumentQuery with
.with_select(Select::Count), optionally adding a
with_where(...) clause; whatever the request shape, this
impl returns a single u64 (the aggregate count). Per-shape
proof dispatch lives in
[super::count_proof_helpers::verify_count_query] — this
impl just sums the verified entries the helper returns.
Empty entries (e.g. a verifier that emitted None for a
queried-but-absent branch) contribute 0 to the sum via
filter_map(|e| e.count).
