杂项

来自“I spent 6 years developing a puzzle game in Rust and it just shipped, AMA”的亮点

本周的特色(crate)

本周的Crate是layoutparser-ort，这是一个LayoutParser的简化版本，用于基于ML的文档布局元素检测。 尽管没有建议，但llogiq 对他的选择感到满意。 你呢？无论你的答案是什么，请提交您的建议并为下周投票！

测试请求

RFC实施的一个重要步骤是让人们尝试实施并提供反馈，特别是在稳定之前。在继续推进之前，以下RFC将受益于用户测试：

• RFCs
  • 本周没有发布测试要求。
• Rust
  • 本周没有发布测试要求。
• Rustup
  • 本周没有发布测试要求。

如果您是一个功能实现者，希望您的 RFC 出现在上面的列表中，请将新的 call-for-testing 标签添加到您的 RFC 中， 并附上一条评论，提供测试说明和/或有关需要测试的功能方面的指导。
