        prompts::{Input, AbortReason},
        DisplayPrompt
    };
 
    fn show_input_prompt() {
      let name : Result<String, AbortReason> = Input::new("Enter your name", name_validation)
          .default_value("John")
          .help_message("Please provide your real name")
          .display();
 
      match name {
          Ok(n) => println!("The name is {}", n),
          Err(abort_reason) => println!("Input was aborted because of {:?}", abort_reason),
      }
    }
 
    fn name_validation(name: &str) -> Result<String, String> {
      if name.len() > 0 {
          Ok(name.to_string())
      } else {
          Err("Name must not be empty".into())
      }
