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。

契约
- assert anyhow captures backtraces with status Captured when RUST_BACKTRACE is enabled
- assert anyhow backtrace status is Disabled when RUST_BACKTRACE is zero or unset
- assert RUST_LIB_BACKTRACE=0 overrides RUST_BACKTRACE=1 to disable anyhow backtrace capture
- assert RUST_LIB_BACKTRACE=1 overrides RUST_BACKTRACE=0 to enable anyhow backtrace capture
- assert anyhow backtrace capture is eager at instantiation time and does not capture retroactively when env changes
- assert Debug formatting appends Stack backtrace only when backtrace status is Captured
- assert Display and Alternate Display format error messages and chains without backtrace frames
- assert anyhow::Error::backtrace provides an inherent method returning a reference to std Backtrace
