这里不会讨论任何非嵌入式的 Rust 特性:见 https://rust-embedded.github.io/book/intro/no-std.html 。 Cpp 用户请注意。Rust 和 Cpp 共享很多术语与概念(所有权、生命周期、析构器、多态性),但 Rust 对它们的实现往往具有明显不同的语义。在 Cpp 中的经验不应该被期望能准确地迁移。 什么是
Rustunit在F#中也是unit. 它们都用()作为其字面量. 这是令Rustacean十分开心的类型. (几乎)任何东西都是表达式! Ruststr在F#中是string. F#文档叫它"字符串是用于表示文本的字符的顺序集合。 对象 String 是表示字符串的对象的顺序集合 System.Char". RustString在F#中是StringBuilder. F#文档: "表示可变字符...
