use clap::{ArgGroup, Clap};

#[derive(Clap, Debug)]
#[clap(group = ArgGroup::new("verb").required(true))]
struct Opt {
    /// Set a custom HTTP verb
    #[clap(long, group = "verb")]
    method: Option<String>,
    /// HTTP GET
    #[clap(long, group = "verb")]
    get: bool,

    let opt = Opt::parse();
    println!("{:?}", opt);
