Struct ResultMetadata 

pub struct ResultMetadata {
    pub execution_time_ms: u64,
    pub rows_scanned: usize,
}

Performance metadata attached to every analytics result.

The dashboard uses execution_time_ms to display the “Avg Query Latency” counter. rows_scanned is useful for understanding query cost (before indexes kick in).

Fields

execution_time_ms: u64

Wall-clock time from query start to result ready, in milliseconds. Measured using web_time::Instant which works in both native and WASM.

rows_scanned: usize

Number of documents that passed the WHERE filter and were included in the metric computation. For COUNT this equals the result; for others it’s the number of documents whose field value was extracted.
