我试图有一个CLI工具，根据一些指定的正则表达式编辑文件。
在调试中，例如：

cargo run -- folder ./tests/test_files -t emails ip

或者在生产中，例如：

raf folder ./tests/test_files -t emails ip

folder是一个子命令，第一个参数是folder的路径，-t或--types参数应该有一个正则表达式类型列表（例如，对应于电子邮件的正则表达式，对应于IP地址的正则表达式等）。
下面是试图实现此目的的结构体列表：

use clap::{Parser, Subcommand, Args};

#[derive(Debug, Parser)]
#[clap(author, version, about, name = "raf")]
pub struct Opts {
    #[clap(subcommand)]
    pub cmd: FileOrFolder,
}

#[derive(Debug, Subcommand)]
pub enum FileOrFolder {
    #[clap(name = "folder")]
    Folder(FolderOpts),
    #[clap(name = "file")]
    File(FileOpts),
}

#[derive(Args, Debug)]
pub struct FolderOpts {
    /// `path` of the directory in which all files should be redacted, e.g. ./tests/test_files
    #[clap(parse(from_os_str))]
    pub path: std::path::PathBuf,

    /// The type of redaction to be applied to the files, e.g. -t sgNRIC emails
    #[clap(short, long)]
    pub types: Vec<String>,
}

#[derive(Args, Debug)]
pub struct FileOpts {
    #[clap(parse(from_os_str))]
    pub path: std::path::PathBuf,
    #[clap(short, long)]
    pub types: Vec<String>,
}

基本上，结构体FolderOpts和FileOpts的字段types是有问题的。
运行时错误为：

... raf> cargo run -- folder ./tests/test_files -t emails ip
    Finished dev [unoptimized + debuginfo] target(s) in 0.26s
     Running `target\debug\raf.exe folder ./tests/test_files -t emails ip`
error: Found argument 'ip' which wasn't expected, or isn't valid in this context

USAGE:
    raf.exe folder [OPTIONS] <PATH>

For more information try --help
error: process didn't exit successfully: `target\debug\raf.exe folder ./tests/test_files -t emails ip` (exit code: 2)

如何将-t emails, ip转换为FolderOpts.types = vec!["emails", "ip"]？
