Struct CaptureMeasurement 

pub struct CaptureMeasurement {
    pub tables: i64,
    pub rows: i64,
    pub bytes: i64,
}

D2/A4: measure the capture BEFORE materializing anything. Ordered probes, aborting on the first violation: table count; per-table row count with a LIMIT maxRows + 1 early-abort probe; a single-row probe for rows larger than maxRowBytes; a bounded SUM over a LIMITed subquery. Only then is anything copied.

Fields

tables: i64

rows: i64

bytes: i64
