Holding references inside structs and enums is where lifetime annotations become unavoidable. This post covers how to annotate data structures that borrow from external data, what the constraints mean in practice, and the design patterns that keep your code clean.

Advanced Rust Series Part 4: Lifetime Elision – What the Compiler Infers and When You Must Be Explicit
Most Rust code compiles without a single lifetime annotation. That is not luck – it is lifetime elision, a set of deterministic rules the compiler applies automatically. Understanding those rules tells you exactly when you need to write annotations and why some errors catch you off guard.
Advanced Rust Series Part 2: Borrowing Rules in Depth – The Borrow Checker Mental Model
The borrow checker is not a random obstacle – it has a clear set of rules and a consistent mental model. Once you internalize how it reasons about your code, you stop fighting it and start working with it. This post breaks down those rules at a level that changes how you write Rust.
