The Clippy failure is unrelated. It's likely that the derived implementation of PartialEq that clippy is highlighting is wrong |

I'm just seeing this now but it's nice! You should have ping me.
You can disable the lint for the impl of Eq at crate level I think it's not relevant here. We don't want to enforce the user to implement Eq on all their types otherwise they won't be able to store f32 and f64 in an IArray

I think you forgot to write a test for this. It's not super important but it makes sure that someone does not remove it by mistake

I'm going to merge this. The test can be added later |
