clap_complete 4.5.1 rpassword: 7.3.1 结论先行 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...
你可以使用values_of方法：
#[arg(short, long, action = clap::ArgAction::Count)] debug: u8, #[command(subcommand)] command: Option<Commands>, } #[derive(Subcommand)] enum Commands { /// does testing things Test { /// lists test values #[arg(short, long)] list: bool, }, } fn quick_test(){ let cli = ...
#[arg(short, long, action = clap::ArgAction::Count)] debug: u8, #[command(subcommand)] command: Option<Commands>, } #[derive(Subcommand)] enum Commands { /// does testing things Test { /// liststestvalues #[arg(short, long)] ...
cargo add clap --features derive 其他派生clap::_features - Rust (docs.rs) 运行这个命令行会在Cargo.toml中添加 clap= { version ="4.2.1", features = ["derive"] } 关于为什么要加features,可以阅读Rust语言圣经中的内容. 或者可以直接手动在Cargo.toml中添加clap库的配置. ...

Part1一、clap_v3 本来是想用structOpt,但是看文档是这样描述的 由于clap v3 现已发布,并且 structopt 功能已集成(几乎按原样),因此 structopt 现在处于维护模式:不会添加新功能。 错误将被修复,文档改进将被接受。 11. 1 添加依赖 [dependencies] clap = { version ="4.2.7", features = ["derive","cargo...
