| <div class="block">Set of schema utilities that don't fit well as methods on the column |
| or tuple classes. |
| <p> |
| Provides methods to check if a column is consistent with the projection |
| requested for a query. Used for scans: the reader offers certain columns |
| and the scan operator must decide whether to accept them, and if so, |
| if the column that has actually appeared is consistent with the projection |
| schema path provided by the planner. An obvious example is if projection |
| asks for <code>a[0]</code> (and array), but the reader offer up <code>a</code> |
| as a non-array column. |
| <p> |
| Checks are reasonable, but not complete. Particularly in the <code>DICT</code> |
| case, projection depends on multiple factors, such as the type of the |
| key and values. This class does not (yet) handle that complexity. |
| Instead, the goal is no false negatives for the complex cases, while |
| catching the simple cases. |
| <p> |
| The Project operator or other consuming operator is the final arbitrator |
| of whether a particular column satisfies a particular projection. This |
| class tries to catch those errors early to provide better error |
| messages.</div> |
