Trait ClapClingExt 

pub trait ClapClingExt: Sized {
    // Required method
    fn into_cling(self) -> Cling<Self, Ready>;
}

Enables clap structs to be executed with cling.

This extension trait allows clap users to parse their clap structs as usual, then run them with cling without constructing a Cling instance explicitly.

Example:

use cling::prelude::*;

#[derive(Run, Parser, Debug, Clone)]
#[cling(run = "run")]
pub struct App {
    /// Turn debugging information on
    #[arg(short, long, action = ArgAction::Count)]
    pub debug: u8,
}


pub async fn run() {
    println!("Hello, world!");
}

#[tokio::main]
async fn main() {
    let app = App::parse();
    let app = app.into_cling();
    app.run_and_exit().await;
}

Required Methods

fn into_cling(self) -> Cling<Self, Ready>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
