Can't get minimal example to work

[bradydean]

Not sure if I'm doing something wrong, or if this package is out of date now. I used it back for aoc 2020 and it worked great. Trying on Rust 1.65.0.

use aoc_runner_derive::{aoc_lib, aoc_generator, aoc};

#[aoc_generator(day1)]
fn input_generator(input: &str) -> Vec<u32> {
    vec![42]
}


#[aoc(day1, part1)]
fn part1(input: &[u32]) -> u32 {
    0
}


aoc_lib!{ year = 2021 }

i tried also another return type than usize and got some problem.
try fn part1(input: &[u32]) -> usize

[duchonic]

maybe same for input, try

#[aoc_generator(day22)]
fn parse_input(input: &str) -> String {
input.to_string()
}

Hi !
Looks like you have incompatible versions of cargo aoc & aoc-runner.
I've updated the example repository to use the last version.

So the steps to fix that:

• Make sure you have the last cargo aoc (cargo aoc --version should yield cargo-aoc 0.3.0)
• Use the last version of aoc-runner & aoc-runner-derive:

aoc-runner = "0.3.0"
aoc-runner-derive = "0.3.0"
