Typestate in Rust: Enforcing State Machine Rules at Compile Time

Functional State Machines in Rust: Typestate and Newtype Patterns

This paper explores how Rust's type system can model state machines, using typestate and newtype patterns to enforce protocol correctness at compile time. It demonstrates encoding states as types and transitions as methods, preventing invalid operations and reducing runtime errors. The approach leverages Rust's zero-cost abstractions, offering a robust alternative to runtime checks for domain logic.
