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
- StreamExt::chunks returns Poll::Pending and withholds buffered items when upstream is pending before filling chunk capacity, whereas ready_chunks yields immediately
- StreamExt::forward feeds stream items into a sink and closes the sink via poll_close upon stream completion rather than leaving it open with poll_flush
- SinkExt::feed buffers items via start_send without triggering poll_flush while send triggers poll_flush on every call
- StreamExt::take_while permanently consumes and drops the first item failing predicate from the underlying stream
- StreamExt::buffered imposes head-of-line blocking preserving stream order whereas buffer_unordered yields in completion order
- select_biased! polls branch futures in top-down order deterministically when multiple branches are ready simultaneously
- FuturesUnordered returns Ready(None) when empty but remains reusable when subsequent futures are pushed
- Abortable resolves to Err(Aborted) when cancelled before completion but retains completed values intact
