🍃 Lifespan

Raito lets you define async startup/shutdown logic using a @rt.lifespan(router) decorator — just like in FastAPI.

---

Example

from typing import AsyncGenerator

from aiogram import Bot, Router,
from raito import rt, Raito

router = Router(name="lifespan")

@rt.lifespan(router)
async def lifespan_fn(raito: Raito, bot: Bot):
    bot_info = await bot.get_me()
    rt.log.info("🚀 Launching bot : [@%s] %s", bot_info.username, bot_info.full_name)

    rt.debug("Registering commands...")
    await raito.register_commands(bot)

    yield

    rt.log.info("👋 Bye!")

---

How it works

• Code before yield runs on startup

• Code after yield runs on shutdown

• Lifespans are tracked per bot.id and executed in reverse order on exit
