Derive Macro Collect 

#[derive(Collect)]

Mark a clap struct/enum to be passed as a handler argument.

Note: Types that implement Collect must also be Clone.

Example:

use cling::prelude::*;
#[derive(Collect, Args, Debug, Clone)]
pub struct Options {
    /// Turn debugging information on
    #[arg(short, long, action = clap::ArgAction::Count)]
    pub debug: u8,
}

// Options must derive `Collect`
fn run(options: &Options) {
   println!("Debug level is {}", options.debug);
}
