    Ralf Jung氏、今度はCoqではなくmiriでRustの安全性バグを見つけたらしい。
    miriはRustの中間言語インタプリタで、インタプリタなので手軽にvalgrind的なチェックをはさみつつ実行できるという利点がある。

      The function allocate_for_ptr is passed a *const [T], which it turns into a &RcBox<[T]>. Unfortunately, the latter has an alignment of 8 even if T has smaller alignment. This leads to UB ...

    1. Announcing Askama 0.7.0
      from The Rust Programming Language Forum
      After two months, I’m happy to announce the 0.7.2 release of Askama, the type-safe, compiled Jinja-like template engine for Rust! Despite the small version number increase (because this release should be fully backwards compatible with earlier 0.7 releases), there’s a good amount of feature in this release. Happily, I can say that for the first time, all of the improvements in this release are due to @botika spending a lot of time on improving Askama over the past months, for which I owe them ma...

    https://internals.rust-lang.org/t/pre-rfc-a-new-symbol-mangling-scheme/8501
    Rustで普通に定義した関数の名前は、Cからは_ZNで始まる英数字列のように見える。これはmanglingといって、複雑な情報を安全な文字だけで表すために行われている。
    今は型引数などの情報をハッシュで圧縮してしまっているが、これをせずC++のようにする方法が提案されている。

      pre-RFC: a new symbol mangling scheme
      from Rust Internals
      This is a proposal for a new name mangling scheme for the Rust compiler. It should solve the known problems of the existing scheme (see the “Motivation” part). The pre-RFC version does not yet include the strict technical description but the “Guide Level Explanation” should give a good idea what it looks like. It would be great to hear what people think; whether it makes sense to fully flesh out the remaining details or if we should take a different approach altogether. Feature Name: symbol_n...

      Good morning everyone! I’d like to both ask for feedback and provide a heads-up about a change to Cargo’s crate index. If you’re a normal user of Cargo, everything will continue working and this can be ignored. As a bit of background, Cargo’s index for crates.io crates lives at a git repository: https://github.com/rust-lang/crates.io-index. This git repository receives a new commit for all new crates published on crates.io. Each git commit adds a line to a file corresponding to the crate that w...

      To the creators of Rust
      from The Rust Programming Language Forum
      I gotta say, I’m pretty speechless today. I had heard about this language called Rust probably about two years ago but at that point, I had no usage for it. I’ve programmed in C, C++, PHP, Python, JavaScript, C#, x86-64 assembly, though I’m most comfortable with C. In my line of work, I’m often performing tasks which are extremely demanding on the memory and CPU cores. For this reason, I’ve never really been able to get into a “higher level” language seriously. At work right now, one of the l...
