本文将从 CLI(Command Line Interface)命令行工具的概述讲起,介绍一个优秀的命令行工具应该具备的功能和特性。然后介绍 Rust 中一个非常优秀的命令行解析工具 clap 经典使用方法,并利用 clap 实现一个类似于 curl 的工具 httpie。文章最后还将 clap 于Go 语言中同样优秀的命令行解析工具 cobra 进行一个简单对比,便...
然后注意Cargo.toml中需要加一下依赖和feature: [dependencies] syn={ version = "2", features = ["full", "parsing"] } quote="1.0" prettyplease = "0.2.12" 运行就是熟悉的cargo run但是输出的玩意儿……一言难尽。如果有知道用这种方法生成AST的大佬,请赐教呜呜呜...

We also use the StructOpt derive macro to automatically generate the code for parsing the command-line arguments into an instance of Opt. Finally, in main, parse the command-line arguments using Opt::from_args(): fn main() { let opt = Opt::from_args(); println!("Using input file: {...
