Advent of Code 2025 — Rust

A collection of my solutions to Advent of Code 2025, written in Rust.
This project serves as a practical way for me to learn Rust deeply by solving progressively harder problems using increasingly idiomatic patterns.

Each day follows a shared interface (Day trait) and a consistent file structure.

• lib.rs: defines the Day trait and shared utilities
• main.rs: command-line entrypoint
• days/dayXX.rs: each day's solution

🎯 Goals

• Learn idiomatic Rust
• Practice:
  • ownership & borrowing
  • lifetimes (when needed)
  • iterators & combinators
  • pattern matching
  • clean module structures
  • error handling
  • testing & benchmarks
• Solve the puzzles in a clean, readable way
• Refactor code as Rust knowledge improves
