Expand description

Result of a fetch query

Fields

num_rows: u64

number of rows returned

columns: Columns

description of columns returned

rows: Vec<u8>

result rows, encoded in CBOR as an array (rows) of arrays (fields per row)

error: Option<SqlDbError>

optional error information. If error is included in the FetchResult, other values should be ignored.
