A beginner-friendly exploration of Rust traits through the lens of buffered vs unbuffered file I/O. Covers the Read and BufRead traits, how BufReader wraps a File, implementing the Read trait on a custom DataProvider struct, dynamic dispatch with Box<dyn Error>, and ownership/borrowing nuances when using iterators like lines(). Includes working code examples and honest reflections on Rust's type system from a self-described Rust noob.
