This question evaluates understanding of string data structures, memory layout, ownership and move semantics in Rust, and algorithmic complexity related to copying and performance.
Question
What is a string in programming languages? Inside a struct string{} in Rust, what fields are stored and how would you design and implement one yourself? If you copy a string, what is the time complexity of the operation? How can move semantics be made more efficient? In Rust, is a move simply a reference update?
