Enum IndexColumn 

#[non_exhaustive]
pub enum IndexColumn {
    TableColumn(IndexColumnTableColumn),
    Expr(IndexColumnExpr),
}

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.

TableColumn(IndexColumnTableColumn)

Expr(IndexColumnExpr)
