Learning Curriculum

Rust taught through game features — each lesson implements one feature that exercises one concept.

# Rust Concept Feature Status

#	Rust Concept	Feature	Status
1	Variables, types, `println!`	Score combo counter for consecutive correct answers	FAIL
2	Functions & return values	`calculate_damage()` with floor-scaling for traps	FAIL
3	Enums & pattern matching	New `Tile::Lava` that damages per-step	FAIL
4	Structs & methods	`Enemy` struct with HP, position, patrol logic	FAIL
5	Ownership & borrowing	Wire enemies into game loop (borrow checker lesson)	FAIL
6	`Option` & `Result`	Save/load game state to JSON	FAIL
7	Iterators & closures	Statistics screen — filter/map/fold over history	FAIL
8	Traits	`Interactable` trait shared by enemies and terminals	FAIL
9	Lifetimes	Custom widget for detailed map view	FAIL
10	Error handling	TOML config file with proper error propagation	FAIL

Each lesson uses crypta’s own code as examples — no abstract exercises
The user writes the implementation; Claude coaches
cargo check is the primary teacher — Rust’s compiler errors are the curriculum
Lessons build on each other — lesson 5 requires understanding from 1-4
