RowsExpected(RowsExpectedError)
QueryResult::first_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
).
RowsEmpty
Rows in QueryResult
are empty
FromRowError(FromRowError)
Parsing row as the given type failed
