Module advent_of_code_2022::day_7

This is my solution for Advent of Code - Day 7 - No Space Left On Device

Parse and recursively walk a directory structure to find the optimal directory to delete

Structs

• Directory 🔒
  Represent a directory in a file system
• File 🔒
  Represent a file in a filesystem
• FileSystem 🔒
  Represent a file system with it’s contents in a tree starting at root and the current working directory in path

Enums

• Command 🔒
  Represent console output as a command to update the state of a FileSystem to match

Functions

• find_directory_size_to_delete 🔒
  Part 2: Find the smallest directory that needs to be deleted to leave 30M units of space free from a total of 70M units of space.
• get_small_dirs_size_sum 🔒
  Part 1: Sum all the directories whose total contents are 100_000 units or less
• parse_commands 🔒
  Turn console lines into structured data representing the change to the file system state indicated by that line of output.
• run
  The entry point for running the solutions with the ‘real’ puzzle input.
