Enum AlterTableSingle 

#[non_exhaustive]
pub enum AlterTableSingle {
    RenameTable {
        new_table_name: &'static str,
    },
    AddColumn {
        column: TableField,
    },
    RenameColumn {

        new_column_name: &'static str,
    },
}

Single alter-table operation used by the migration procedural macros.

This enum is not intended to be constructed manually in user code; the Table macro generates these values when compiling migrations.

⚠️ API instability

This type is marked as #[non_exhaustive] and will be changed in the future. Prefer to rely on the macros instead of matching all variants.

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.
