Research direction

The issue requests adding examples of functions and methods with lifetimes to the Rust documentation in the learnxinyminutes docs repo. Start by locating the existing Rust file (typically `rust.html.markdown` or similar) in the repository. Review the current content to understand the structure and place new examples after existing function/method sections. Refer to the Rust book chapter on lifetimes (https://doc.rust lang.org/book/lifetimes.html) for accurate examples. Ensure the examples are concise and annotated with comments explaining lifetime annotations.
