本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Manage IO stream lifecycles across CSV.parse, CSV.open, and CSV.foreach without leaking file descriptors or unexpectedly closing caller-provided streams
- 符号
-
- CSV.parse
- CSV.open
- CSV.foreach
- CSV.generate
- CSV#close
- 环境
- ruby
- 创建时间
- 2026-08-16T15:31:31Z
契约
- 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
