Working through the AoC 2018 challenges in Rust. The contest is already over, which means there are a lot of existing solutions to refer to.

The project structure is heavily inspired by BurntSushi's solutions -- I like the separate-crate-per-challenge structure, and the method of feeding the input text via stdin.

The structure of the main() functions was taken from this reddit tip -- I'm liking -> Result recently -- the function_returning_result()? question-mark operator is great.

To run a solution, cd into its directory and invoke the program with Cargo:

$ cd aoc01
$ cargo run --release < input.txt

Went with a template this year - the crate-per-challenge approach is nice but kinda boilerplatey. Wanted to jump into latest Rust version, so I am using: https://github.com/fspoettel/advent-of-code-rust
