Other bugs & improvements

Rust

derive(PolarClass) is now supported on Rust enums

Rust enums can use the PolarClass derive macro to register as a Polar class. Variants of the enum are registered in Polar as constants. For example, the enum:

#[derive(Clone, Debug, PartialEq, PolarClass)]
enum Role {
    Admin,
    Member,
}

is referenced in Polar as:

allow(actor, _, resource) if actor.role == Role::Admin;

Only unit variants are supported currently. Thanks to @seanchen1991 for this contribution!

Other bugs & improvements

  • Fixed bug in authorize_model leading to data filtering queries to have a filter even when one policy result was unconditionally true.
