Explain strings, moves, and concurrency

This question evaluates understanding of string data structures, ownership and move semantics (including Rust-specific move behavior), and concurrency models such as threads versus asynchronous coroutines, testing competencies in memory management, performance analysis, and concurrent programming.
Question
What is a string in programming languages? What fields are stored in a typical struct string and how would you implement one yourself? What is the time complexity of copying a string? How can move operations be made more efficient? In Rust, does move only modify the reference? What is the difference between a thread and an asynchronous coroutine?
