launch.json rust in vscode

在第一个JSON文件中，参数是[ "build", "--bin", "unsafe-counter"]。cargo build --bin unsafe-counter命令是用于构建二进制文件unsafe-counter的。在这个配置中，VSCode将会构建这个应用程序，然后使用参数"/root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs"来启动它。注意，这种方式需要你的程序能接受并处理这个参数。

在第二个JSON文件中，参数是[ "run", "--release", "--bin", "unsafe-counter", "--", "/root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs" ]。cargo run --release --bin unsafe-counter -- /root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs命令将会在release模式下运行这个二进制文件，并且给它传递"/root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs"参数。然而，这种方式存在一个问题，这就是你没有指定在哪个工作目录下运行这个命令。你需要确定你的unsafe-counter二进制文件是在/root/lab/unsafe-counter目录下，而且它能在那里找到所有它需要的资源。否则，你可能会得到一些关于找不到文件或目录的错误。

为什么json1对
{
    "version": "0.2.0",
    "configurations": [
      {
        "sourceLanguages": ["rust"],
        "type": "lldb",

            "kind": "bin"
          }
        },
        "args": ["/root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs"],
        "cwd": "/root/lab/unsafe-counter"
      }
    ]
}

json2错
