我使用clap v3.1.18，代码如下。

#[derive(Parser, Debug)]
#[clap(author, version, about = ABOUT_TEXT, long_about = Some(ABOUT_TEXT))]
struct Args {

    /// The root folder on local filesystem to scan
    #[clap(short, long, default_value_t = utils::get_current_dir())]
    folder: String,

    /// Max number of recursive folders to scan
    #[clap(short, long, default_value_t = 5)]
    depth: u8,

    /// Regular expression to include files. Only files whose name matches the specified regexp will be listed. E.g. to only list *.dll and *.exe files, you can specify `((\\.dll)$)|((\\.exe)$)`
    #[clap(short, long, default_value(".+"))]
    include: String,

    /// Regular expression to include files. Regular expression to exclude files and directories. Files or directories whose name matches this regexp will be skipped
    #[clap(short, long, default_value("(^~)|(^\\.)|((\\.tmp)$)|((\\.log)$)"))]
    exclude: String,

    /// Command line to start child process
    #[clap(multiple_occurrences=true, use_delimiter=false)]
    command: String,
}
let args = Args::parse();

字符串
最后一个command，我想在命令行中得到所有剩余的部分，包括空格。但是当前代码不起作用，它被第一个空格终止。
我想我应该设置.setting(AppSettings::TrailingVarArg)，但是在派生API中找不到这样做的方法。请问如何才能做到这一点？
感谢@MeetTitan，这是我的代码finnally作品

#[derive(Parser, Debug)]
#[clap(author, version, about = ABOUT_TEXT, long_about = Some(ABOUT_TEXT), trailing_var_arg=true)]
struct Args {

    /// The root folder on local filesystem to scan
    #[clap(short, long, default_value_t = utils::get_current_dir())]
    folder: String,

    /// Max number of recursive folders to scan
    #[clap(short, long, default_value_t = 5)]
    depth: u8,

    /// Regular expression to include files. Only files whose name matches the specified regexp will be listed. E.g. to only list *.dll and *.exe files, you can specify `((\\.dll)$)|((\\.exe)$)`
    #[clap(short, long, default_value(".+"))]
    include: String,

    /// Regular expression to include files. Regular expression to exclude files and directories. Files or directories whose name matches this regexp will be skipped
    #[clap(short, long, default_value("(^~)|(^\\.)|((\\.tmp)$)|((\\.log)$)"))]
    exclude: String,

    /// Command line to start child process
    #[clap(long, multiple_values=true, allow_hyphen_values=true)]
    run: Vec<String>,
}
