//! `Mingling` Example - Basic

//! # How to Run
//! ```bash
//! cargo run --manifest-path ./examples/example-basic/Cargo.toml -- hello World
//! ```
use mingling::{
macros::{chain, dispatcher, gen_program, pack, r_println, renderer},
marker::NextProcess,

// Run program

// Register chain to `DefaultProgram`, handling logic from `HelloEntry`

#[renderer]
fn render_hello_who(prev: Hello) {
// Print message
r_println!("Hello, {}!", *prev);
// Program ends here
}
// Generate program, default is `DefaultProgram`
