}
Variants
RowsExpected(RowsExpectedError)
QueryResult::single_row_typed()
called on a bad QueryResult.
Expected QueryResult.rows
to be Some
, but it was None
.
QueryResult.rows
is Some
for queries that can return rows (e.g SELECT
).
It is None
for queries that can’t return rows (e.g INSERT
).
BadNumberOfRows(usize)
Expected a single row, found other number of rows
FromRowError(FromRowError)
Parsing row as the given type failed
