fn jsonb_uint64_to_log_value(u: u64, column_name: &str) -> Result<i64>Expand description
Converts a JSON UInt64 number into the signed value used by built-in
log columns. JsonbNumber::UInt64 only arises for values that do not fit
in i64 (see decide_column_schema_and_convert_value), so the conversion
is fallible: wrapping to a negative number would silently corrupt the
value (a counter reading back as negative), so out-of-range values are
rejected instead.
