What's the difference of derive from Iden and DeriveIden?

[npuichigo]

#[derive(Iden)]
enum Post {
    Table,
    Id,
    Title,
    Text,
}

vs

#[derive(DeriveIden)]
enum Post {
    Table,
    Id,
    Title,
    Text,
}

and which is perfered?

They both implement the same Iden trait.

DeriveIden is exported by SeaORM, which makes it possible to do things without importing SeaQuery. So if you are using SeaQuery directly, use Iden or IdenStatic. SeaQuery's Iden macro also has more macro attributes, e.g. #[iden(flatten)].
