# Objective `approx` has traits like [`AbsDiffEq`](https://docs.rs/approx/latest/approx/trait.AbsDiffEq.html), [`RelativeEq`](https://docs.rs/approx/latest/approx/trait.RelativeEq.html), and [`UlpsEq`](https://docs.rs/approx/latest/approx/trait.UlpsEq.html). Glam implements them for its math types when the `approx` feature is enabled. Bevy's `Direction2d` and `Direction3d` should implement these too. ## Solution Implement the traits. See [how Glam implements them for its own math types](https://github.com/bitshifter/glam-rs/blob/main/src/features/impl_approx.rs). For the epsilon values, I use the same as `Vec2`/`Vec3` (just `f32::EPSILON`).
