Borrow Checker Patterns about patterns HOT 2 OPEN

Would be nice if we could collect some ideas of which topics/quirks to cover or, in general, what would be a reasonable approach to the overall topic of borrow checker patterns.

from patterns.

I feel like to fully understand borrow & checker, we should cover the following topics :

• Explanation of Borrowing Rules: While Rust's borrowing rules are documented, it would be helpful to have more in-depth explanations and examples that show these rules in action.

• Common Borrow Checker Errors: A guide to common borrow checker errors, their causes, and how to resolve them could be very helpful for new Rust developers.

• Borrowing in Different Contexts: Borrowing behaves differently in different contexts (e.g., in struct fields, in loops, in closures). Each of these could be a topic of its own.

• Patterns for Avoiding Borrow Checker Errors: Some coding patterns can help avoid borrow checker errors. For example, splitting functions, using Rc and RefCell for shared ownership, or using the Cow type for efficient cloning.

• Understanding Lifetimes: Lifetimes are a crucial part of the borrow checker, but they can be confusing for newcomers. More resources on understanding and using lifetimes could be very valuable.

• Move semantics: Lastly, we should also provide some materials with regard to the concept of move. Speak of this, I found rustlings exercise on move semantics very useful.

@simonsan What's your thoughts on this ?
