No warnings ... though `delayed_good_path_bugs` issued

[0adb]

(I'm not sure if I should be filing this issue. The instructions in the template say that if the error is encountered with the stable version of the compiler, that I should check that the error exists on nightly/beta. The error below does go away with nightly/beta, but the instructions in the template don't say if that means I shouldn't file the issue anymore or just note that the error goes away on nightly/beta. Apologies if it's the former.)

Code

in src/main.rs:

use std::{process, env};
use rust_advent_2019::{Config, run};
mod day1;

fn main() {
    let args: Vec<String> = env::args().collect();
    let config  = Config::new(&args).unwrap_or_else(|err| {
    println!("Problem in parsing args: {}", err);
    process::exit(1);
    });
    run(config);
}

in src/lib.rs:

use std::error::Error;

pub mod day1;

pub struct Config {
    pub day: String,
    pub extra_args: Vec<String>,
}

impl Config {
    pub fn new(args: &[String]) -> Result<Config, &'static str> {
    let split_args = args.split_first();
    match split_args {
        None => Err("missing first argument"),
        Some((first, elements)) => Ok(Config { day: first.clone(), extra_args: elements.to_vec()}),
    }
    }
}

pub fn run(config: Config) -> Result<(), Box<dyn Error>> {
    panic!("unimplemented");
}

in src/day1.rs

pub fn solve() {
   println!("called day 1 solve!");
}

I think this is a duplicate of #97173, and it's indeed fixed on beta/nightly.

but the instructions in the template don't say if that means I shouldn't file the issue anymore or just note that the error goes away on nightly/beta.

If the issue tracker has a similar issue and it's closed as fixed, you don't have to open an issue. But if you're unsure, I think it's totally okay to open a new issue, contributors will check if it's reported in the past, gets fixed, etc.

This time I'm going to close as the issue has been fixed already. Thanks for reporting!
