Struct ResultSet
A random access range of Row.
struct ResultSet
;
This is being considered for deprecation in a future release of mysql-native,
because the same thing can be achieved by passing a ResultRange to
std.
This is returned by the querySet and
PreparedImpl functions.
Unlike ResultRange, this offers random access to the individual rows via
array-like indexing and a length member to check the number of rows received
without having to count them.
However, this random access comes with a downside: Unlike ResultRange, using
ResultSet means ALL the rows are downloaded and stored in
memory before you can access any of them. So use this only if you really need
random-access and you're not likely to be dealing with large numbers of rows.
Otherwise, consider using query to receive a ResultRange instead.
