Struct ResultRange
An input range of Row.
This is returned by the mysql and
mysql functions.
The rows are downloaded one-at-a-time, as you iterate the range. This allows for low memory usage, and quick access to the results as they are downloaded. This is especially ideal in case your query results in a large number of rows.
However, because of that, this ResultRange cannot offer random access or
a length member. If you need random access, then just like any other range,
you can simply convert this range to an array via
std.
Or, you can use querySet to obtain a ResultSet instead.
