This macro is the perfect way to assert conditions in example code and in tests. panic! is closely tied with the unwrap method of both`Option`[3] and `Result`[4] enums. Both implementations callpanic! when they are set to [None] or [Err] variants. When using panic!() you can spec...

宏(Macro)是 Rust 编程语言的重要组成部分。它是一种扩展编译器功能的方法,从而可以支持标准之外的功能。 从根本上说,宏是一种编写代码来生成其他代码的方法,被称为 元编程(Metaprogramming)。 宏允许你在编译阶段生成代码,通过macro_rules!或proc_macro来定义,打破了常规代码的静态限制,让你的代码在编译时就能根据...
