Module 2: Advanced Generics

Higher-ranked trait bounds (for<'a> syntax)
Associated types vs generic parameters — when to use which
PhantomData and type-level programming
Hands-on: Build a type-safe builder pattern with compile-time validation

Module 3: The Type State Pattern

Encoding state machines in the type system
Preventing invalid state transitions at compile time
Zero-sized types for state markers

thiserror and anyhow in library vs application code
Error context and backtraces
Hands-on: Design an error handling strategy for a multi-layer application

Day 2: Macros and Metaprogramming

Module 5: Declarative Macros

macro_rules! patterns and repetitions
Fragment specifiers and macro hygiene
