crate-name— crate 的名称。 file-names— 文件名由link命令执行的种类所决定。 sysroot— 系统根目录路径。(译者注:此处指的是所使用 rust 根目录即.rustup 下的 toolchains 文件夹) target-libdir- 目标 lib 文件夹路径(译者注:同上)。 cfg— 条件编译值列表。 了解更多条件编译值信息,请参阅条件编译。
Command-line arguments refer to a set of values or specifiers that are passed to the name of a terminal program. These arguments can hence modify the behavior of the program as defined in the source code. For example, you can pass the directory you wish to list to the ls command. Hence...
This implements a straightforward form where each argument is on a separate line in a text file. This allows for everything except for arguments with internal line breaks. Description (also in docs) If you specify @path on the command-line, then it will open path and read command line opti...
这也包含了Rust运行时情况。To force Rust to dynamically link programs, use the command-line arguments -C prefer-dynamic; this will result in a much smaller file size but will also require the Rust libraries (including its runtime) to be available to your program at runtime. This essentially ...

可以看到对于ifun-grep一个基本的使用方式,包括Usage、Arguments、Options。还展示了对于结构体Config的注释说明、例子。 通过简写的-h可以让描述更加紧凑一点。 clap 通过#[command()]可以从Cargo.toml获取到一些基础信息,生成 Command 实例 #[derive(Parser)] ...
