#[command]: Provides metadata like the name, version, and description of the application. #[arg]: Configures individual arguments, such as short for -v and long for --verbose. 3. Parsing Arguments: Cli::parse() parses the command-line inputs and maps them to the Cli struct. 4. Access...

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...
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...
Overall, while usingstd::env::argscan work for simple command-line arguments, it is recommended to use a dedicated command-line argument parsing library likeclaporstructoptfor more complex command-line interfaces. These libraries provide a more robust, flexible, and maintainable solution for handling...
Command-line parsing is essential for any program that needs to be run by other people, and is a messy task with many corner cases: this is one wheel that should not be reinvented for a project. It should not to be too ugly to use, either, like the getopt_long POSIX interface for ...
