흔히 이렇게 알고 있다

CSV.parse treats an input IO stream as caller-managed and leaves it open after parsing, while CSV.open and CSV.foreach automatically release underlying file handles.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• CSV.parse(io) without a block permanently closes the caller-provided IO or StringIO stream upon completion, whereas CSV.parse(io) with a block leaves the stream open
• CSV.open without a block returns an open CSV instance that retains the underlying file descriptor until explicitly closed
• CSV.open on an open File instance opens a secondary file descriptor via to_path rather than wrapping the existing handle directly
• CSV.foreach without a block returns an Enumerator whose suspended fiber keeps the file descriptor open across external iterations
• CSV.generate with an existing String buffer mutates the input string in place rather than allocating an isolated buffer
