为什么值得看
Bun 的 Rust 代码库被指出无法通过最基本的 Miri 检查,存在 safe Rust 中的未定义行为。这对标榜高性能和安全的 JavaScript 运行时是一记重击,也暴露了大规模 Rust 项目在安全抽象上的真实挑战。
编辑判断
Bun 此前以 Zig + Rust 混合架构作为性能卖点,与 Node.js 和 Deno 竞争。这次 issue 的杀伤力在于它攻击的是 Rust 最核心的品牌承诺——safe Rust 的内存安全保证。如果 safe 代码里都能藏 UB,Bun 相比 C++ 实现的 Node.js 的差异化优势会被削弱。
更深层的问题是,大型项目里 Rust 与 Zig/C 的 FFI 边界、以及 unsafe 块的审计盲区,可能是比语言本身更脆弱的环节。如果你在评估 Bun 用于生产环境,建议关注官方对此 issue 的回应速度和修复透明度,这比漏洞本身更能说明项目的成熟度。

核心争论:Rust重写是否应被过早宣传为"内存安全",以及工作进度代码遭舆论放大的合理性
There's a book that changed a lot of the way I think about attention and media [0]. The book isn't very good, but it flags something relevant here. There is a huge asymmetry between the reach of a big, flashy announcement (here: bun was re-written in memory-safe rust in a couple weeks), and the rela
Not just marketing and PR, the mainstream media knows that pushing out BS and then retracting it later can have lasting effects because people will remember the original article / headline, and never see the correction.
only the mainstream media knows about this? Quite odd to qualify media this way here, when most of all media uses this mechanism. We also forgot politicians who are experts in this field.
