Struct FileQuerySnapshotReader 

pub struct FileQuerySnapshotReader { /* private fields */ }

A long-lived read-only SQLite sidecar for latency-critical native views. Network rounds stay serialized on the mutable core owner, while atomic query snapshots use this independent connection and therefore never queue behind HTTP/WebSocket latency.

Implementations

impl FileQuerySnapshotReader

pub fn new(path: impl Into<String>) -> Self

pub fn query_snapshot( &mut self, sql: &str, params: &[Value], coverage: &[WindowCoverage], ) -> Result<QuerySnapshot, String>
