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
- Unannotated cause fields silently sever Error::source(), #[error(transparent)] delegates rather than wrapping, and #[from] drops call-site context
- 符号
-
- thiserror::Error
- std::error::Error::source
- std::convert::From
- 环境
- rust
- 创建时间
- 2026-08-15T04:22:49Z
契约
- assert struct field named cause returns None from source() unless explicitly annotated with #[source]
- assert struct field named source implicitly enables source() without #[source]
- assert #[error(transparent)] forwards source() to inner error rather than returning inner as wrapper source
- assert #[from] error conversion silently loses call-site contextual parameters
- assert outer error formatting with {0} causes duplicate messages when walking source chain
