Advent of Code Rust utilities

About

This crate provides a very minimal set of utils to get started with writing Advent of Code solutions.

This is a wrapper over an input source (either a file or STDIN). It can be conveniently constructed by parsing cmdline arguments.

Here is an example help printout generated from a program that uses BufferedInput:

```console Example description

USAGE: prog [FILE]

FLAGS: -h, --help Prints help information -V, --version Prints version information

ARGS: Input file (defaults to STDIN if not provided) ```

Collect all lines from input:

```rust use std::io::BufRead; use aoc_utils::BufferedInput;

let input = BufferedInput::parse_args("Example solution").unwrap(); let lines: Vec = input.lines().map(Result::unwrap).collect();

for line in lines { println!("{}", line); } ```
