Thanks a lot for the suggestion, I can't believe I didn't know about this. However I just tried it and I can't get it to work.

I added this to the top of https://github.com/etesync/etebase-rs/blob/master/src/lib.rs and then ran `cargo clippy`

    #![warn(clippy::all)]

    // Should fail https://rust-lang.github.io/rust-clippy/master/index.html#float_cmp
    pub fn bool_test(x: f32, y: f32) -> bool {
        x == y
    }

Any idea what's missing? Why is it not failing?

Edit: I know the above example is bad code, that's the point. I want clippy to complain about it but it doesn't.
