How to Create an Indexed Column?

[celestialorb]

I'm unable to figure out how to create an indexed column as part of the schema for a table.

I imagine it could be something as simple as:

using ObjectTable = zxorm::Table<"objects", Object,
    zxorm::Column<"id", &Object::id, zxorm::PrimaryKey<>>,
    zxorm::Column<"indexed_column", &Object::id, zxorm::Index<>>,
    zxorm::Column<"some_text", &Object::some_text>
>;

In a somewhat related issue as well, I can't figure out how to create a table without a primary key, or with an auto-incrementing primary key. If I remove the zxorm::PrimaryKey<> specification from the id column I end up with compiler errors.
