Primary Key with multiple columns?

[ghost]

Similar to this question but for primary keys. How would it be?

It should be possible to do something like this

et index = Index::create()
    .name("idx-glyph-aspect")
    .table(Glyph::Table)
    .col(Glyph::Aspect)
    .col(Glyph::Ratio)
    .primary()
    .to_owned();
