use diesel_adapter::casbin::prelude::*;
use diesel_adapter::DieselAdapter;

#[async_std::main]
async fn main() -> Result<()> {
    let mut m = DefaultModel::from_file("examples/rbac_model.conf").await?;
    let a = DieselAdapter::new()?;
    let mut e = Enforcer::new(m, a).await?;
    Ok(())
}

Features

Attention: postgres and mysql are mutual exclusive which means that you can only activate one of them. Currently we don't have support for sqlite, it may be added in the near future.
