document_split_sums.rs

1//! `FromProof` + `Fetch` for [`DocumentSplitSums`] — the
2//! per-group-entry view of the unified `getDocuments` endpoint
3//! for sum queries.
4//!
5//! Sum-side analog of [`super::document_split_counts`]. Returns
6//! the full `entries` list (keyed by the splitting property's
7//! serialized value); aggregate sums use
8//! [`super::document_sum::DocumentSum`] instead.
9//!
10//! Per-shape proof dispatch lives in
11//! [`super::sum_proof_helpers::verify_sum_query`] — this impl
12//! passes the verified entries through unchanged, mapping
13//! `SumEntry` to `SplitSumEntry`.
