rainier-console

The console kernel: an [Arguments] parser, a [Command] contract, and the [Console] that dispatches between them — Rainier's artisan.

use rainier_console::{Arguments, Command, Console};
use rainier_container::Application;
use rainier_support::Result;

struct Inspire;

#[async_trait::async_trait]
impl Command for Inspire {
    fn name(&self) -> &str { "inspire" }
    fn description(&self) -> &str { "Print an inspiring quote" }

    async fn handle(&self, _args: &Arguments, _app: &Application) -> Result<i32> {
        println!("Simplicity is the ultimate sophistication.");
        Ok(0)
    }
}

# #[tokio::main] async fn main() {
let console = Console::new("rainier").register(Inspire);
let app = Application::new(".");

assert_eq!(console.run_argv(&app, ["inspire"]).await, 0);
# }

This crate deliberately knows nothing about routing, queues or databases — it depends only on the container. The concrete commands (route:list, serve, migrate, queue:work) live in the rainier crate, which already depends on everything they need. That keeps a console usable in an application that has no HTTP layer at all.
