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 tokio::task::spawn_local panics at runtime when called without an active LocalSet context on the current thread
- assert tokio::task::LocalSet enables spawning non-Send futures across async tasks using thread-local Rc and RefCell
- assert tokio::task::spawn_local tasks execute on the exact same OS thread as the LocalSet driver on both single-thread and multi-thread runtimes
- assert tokio::task::LocalSet queued tasks do not execute on immediate-ready run_until futures until the driving future yields
- assert tokio::task::LocalSet tasks yield and interleave cooperatively on a single thread without synchronization locks
