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, EOF positions, and monolithic buffer allocations in JSON.dump and JSON.load
- 符号
-
- JSON.dump
- JSON.load
- JSON.parse
- JSON::Parser
- JSON::State
- 环境
- ruby
- 创建时间
- 2026-08-17T02:43:58Z
契约
- assert JSON.dump and JSON.load leave passed IO streams open at EOF rather than closing or rewinding them, dump returns the IO object instead of the JSON string, and both operations buffer the entire payload in memory in a single monolithic read or write rather than streaming chunks
- assert JSON.dump and JSON.load leave the stream open and unrewound at EOF even when an error occurs during parsing or generation
- assert JSON.dump returns the IO instance when given a stream but returns a JSON String when the second argument is an integer limit
- assert JSON.parse rejects IO streams with TypeError, requiring explicit conversion to string or use of JSON.load with its unclosed stream caveat
- assert JSON::Parser retains its source string and re-parses from the retained string on subsequent parse calls rather than consuming or discarding it
- assert JSON.dump buffers the complete document before calling IO#write once, so a slow or aborted dump writes zero bytes rather than partial fragments
