Enum DiagnosticCode 

#[non_exhaustive]
pub enum DiagnosticCode {
    ColumnAdded,
    ColumnRemoved,
    ColumnTypeChanged,
    ColumnAllNull,
}

Stable identifier for a kind of schema change.

Part of the serialized contract, like CheckCode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ColumnAdded

The report profiled a column the baseline did not. Without a reason, the baseline profiled every column it selected that its source had, and this was not among them.

ColumnRemoved

The baseline profiled a column the report did not. Without a reason, the report’s selection included it, so it was not in what the report read. With one, the report’s column selection left it out or was not recorded.

ColumnTypeChanged

The column holds values on both sides and its inferred type differs. A column whose values are all null on a side establishes no type there.

ColumnAllNull

The column held values in the baseline, and every value read for it in the report is null.
