Struct Query 

pub struct Query {
    pub start: usize,
    pub end: usize,
    pub sort: Option<SortSpec>,
    pub filter: Option<Filter>,
}

A lazy, virtualized query against the data plane.

start/end, sort, and filter describe what the frontend wants now — the store returns a bounded page, never a full materialization of every object. The window is a plain start/end pair (not std::ops::Range<usize>) so it serializes stably over the wire.

Fields

start: usize

Inclusive window start (e.g. 400 for a virtualized table window).

end: usize

Exclusive window end (e.g. 460).

sort: Option<SortSpec>

Sort key and direction (column id + descending flag).

filter: Option<Filter>

Filter predicate in a stable, serializable form (not a closure — it must cross the serve/gRPC-Web boundary).
