Module advent_of_code_2023::day_1

This is my solution for Advent of Code - Day 1: Trebuchet?

parse_line does most of the heavy lifting, using the provided regex to find digits in a line, and then turn those into a calibration value. It defers to overlapping_matches to handle getting regex matches that might overlap. sum_calibration_values reduces the values into the final puzzle answer.

ValueExtractors are used to codify the different logic for the two parts, see part_1_extractor and part_2_extractor.

Structs

• ValueExtractor 🔒
  Describes how to find digits in a string, and how to turn those into their numeric representation

Functions

• overlapping_matches 🔒
  Return regex matches that might overlap
• parse_line 🔒
  Use the logic in the provided extractor to find all matches, then take the first and last and combine them into a two digit number.
• part_1_extractor 🔒
• part_2_extractor 🔒
• run
  The entry point for running the solutions with the ‘real’ puzzle input.
• sum_calibration_values 🔒
  Reduce the value extracted in each line to the sum required as the puzzle answer.
