AsyncMysqlRowBlock

Represents a row block

A row block is either a full or partial set of result rows from a MySQL query.

In a query result, the sum total of all the row blocks is the full result of the query. Most of the time there is only one row block per query result since the query was never interrupted or otherwise deterred by some outside condition like exceeding network packet parameters.

You can get an instance of AsyncMysqlRowBlock via the AsyncMysqlQueryResult::rowBlocks() call.
