Struct RangeCountOptions 

Source 
pub struct RangeCountOptions {
    pub distinct: bool,
    pub limit: Option<u32>,
    pub order_by_ascending: bool,
}
Expand description

Pagination + ordering knobs for execute_range_count_no_proof.

Mirrors the protobuf request fields on GetDocumentsCountRequestV0 so the drive-abci handler can pass them through unmodified. distinct = false collapses the range walk to a single summed entry; distinct = true returns one entry per distinct property value within the range.

Fields§

§distinct: bool

When true, return one SplitCountEntry per distinct property value within the range. When false, return a single entry (empty key) summing all per-value counts.

§limit: Option<u32>

Maximum number of entries to return. Only meaningful when distinct = true. None means no limit.

To paginate, callers narrow the range itself (color > <last-key-from-previous-page>). There’s no cursor field because a single-bytes cursor would be ambiguous for compound (In + range + distinct) queries whose natural sort is (in_key, key), and range narrowing has the same expressivity for the simple cases.

§order_by_ascending: bool

Sort order for distinct entries. true (default) is ascending by serialized key bytes. Ignored when distinct = false.
