Wrong number of type arguments: expected 1, found 2

error[E0107]: wrong number of type arguments: expected 1, found 2
   --> src/day3.rs:101:1
    |
101 | #[aoc(day3,part1)]
    | ^^^^^^^^^^^^^^^^^^ unexpected type argument

I've started running into this issue now that I've hit day 3 (only discovered AoC around Christmas.

My solver functions in question look like this:

pub fn solver_part1(input: &[Claim]) -> usize {
    let mut g = Grid::new();
    for claim in input {
        for p in claim.iter_points() {
            *g.entry(p).or_default() += 1;
        }
    }
    g.values().filter(|&&count| count > 1).count()
}

I've got the first two days solved just fine and I can't tell what's causing the problem.

I just ran into this issue too, doing old aoc. What fixed it for me was removing use json::*; ( reference to the third party crate json) from the top of the file.

No idea why that would be causing this, but it does work now. I'll try and take a look and see if I can figure out why this is breaking it in a few weeks when I'll have some more time.

Oh, it might have something to do with re-exported Result types, I'm planning a new release before December 1st, and I'll make sure to use full path results each time !

Thanks a lot for reporting ;)
