Day 5: "Supply Stacks"
Interesting part of this puzzle was parsing the multi-part input. Ended up using Serde https://serde.rs and Recap https://github.com/softprops/recap crates for parsing lines to structs using regex named capture groups. Worked really well for this type of free-form input text.
