error: Could not compile `multigroup`.

To learn more, run the command again with --verbose.

My code is about 500 lines long. I'm running up against an assignment deadline, so I don't have time right now to make a minimal demonstration. But if needed I can do so after Thursday, if someone hasn't gotten to it already.

Sorry to dump and run. I normally try to be better about bug reports. :/

I expect this to be related to my copy paste error with repeated if clause: (if r != 0.0(r != 0.0) {1.0} else {0.0});

EDIT: Removed code, as there is a minimal example below.

Minimal example:

fn main() {
    let a = |r: f64| if r != 0.0(r != 0.0) {1.0} else {0.0};
}

Gives output:

error[E0618]: expected function, found `{float}`
 --> test.rs:2:30

2 |     let a = |r: f64| if r != 0.0(r != 0.0) {1.0} else {0.0};
