如何将std :: process :: Command转换为命令行字符串？ [英] How can I convert a std::process::Command into a command line string?

问题描述

例如：

let mut com = std::process::Command::new("ProgramA");

com.env("ENV_1", "VALUE_1")
    .arg("-a")
    .arg("foo")
    .arg("-b")
    .arg("--argument=bar");

// Get the command line string somehow here.

com.output().unwrap();

这将使用此命令行生成一个进程 ProgramA -a foo -b --argument = with space 与之关联。

This will spawn a process with this command line "ProgramA" -a foo -b "--argument=with space" associated with it.

是否有办法将其从<$ c中删除$ c> com 对象？

Is there a way to get this back out from the com object?

推荐答案

原来是 Command 实现 Debug ;

let answer = format!("{:?}", com);
