Advent of Code 2017

I'm doing some Advent of Code stuff, mostly in Rust.

Build with cargo build as normal.

Run like adventofcode2017 DAY, i.e. adventofcode2017 1 to run the day 1 solver.

Input is expected on stdin: adventofcode2017 1 < day01.txt

To Do

• Refactor some for loops into functional paradigms
• Remove the runtime assert!s and instead write tests
• Refactor some items (Count iterator, for example) into a util module
