From what I can see in Facebook's rust-shed repo, it looks like they're happily using the current edition (2021) in their build system. The exact compiler version, I'm not sure of, but as long as it's the 2021 edition I suspect they could be using the current compiler. Unless th...
Rust also haseditions: the current edition is Rust 2021. Previous editions were Rust 2015 and Rust 2018. The editions are allowed to make backwards incompatible changes to the language. To prevent breaking code, editions are opt-in: you select the edition for your crate via theCargo.tomlfile....
rust-version = "1.56" 还有一点,rust-version必须比第一个引入edition的 Rust 版本要新。例如 Rust Edition 2021 是在 Rust 1.56 版本引入的,若你使用了edition = '2021'的[package]配置,则指定的rust version字段必须要要大于等于1.56版本。 还可以使用--ignore-rust-version命令行参数来忽略rust-version。 该...

目前我们代码都是基于内存安全的,并且会在编译阶段进行限制报错不安全代码。 不过rust还内置隐藏了一个(second language)第二语言,它不会强制要求内存安全。 它就是unsafe Rust, 写法和安全的差别不大,但是可以让我们使用额外的”超能力(superpowers)“。
