Struct DocumentSplitSums 

Source 
pub struct DocumentSplitSums(pub Vec<SplitSumEntry>);
Expand description

Verified sum result types. Sum-side analogs of DocumentCount / DocumentSplitCounts; see their respective module docs for the grovedb PR 670 dependency status. The full per-entry sum result, verified from proof.

§0: Vec<SplitSumEntry>

Implementations§

Source§

impl DocumentSplitSums

Source

pub fn try_into_flat_map(self) -> Result<BTreeMap<Vec<u8>, i64>, Error>

Convenience: collapse compound (in_key, key) entries into a flat BTreeMap<key, summed_sum> by combining each In-fork’s contribution at the same terminator key. Same shape as DocumentSplitCounts::into_flat_map on the count side.

Uses i64::checked_add on each accumulator step and surfaces overflow as Error::RequestError rather than panicking (debug) or wrapping (release). Mirrors the SDK’s aggregate-side DocumentSum::fold_sum_entries so a wasm caller that collapses split sums lands at the same hardening boundary the SDK aggregate path already enforces.

On overflow, drop back to iterating DocumentSplitSums.0 directly — per-branch entries preserve the verified i64 values, and the caller can fold with its own arithmetic (e.g. i128).
