How does Litestar provide production-grade ASGI features like plugin systems and OpenAPI v3.1 support that make it superior to FastAPI for enterprise-scale APIs?

# Litestar: Enterprise-ready out-of-the-box
from litestar import Litestar
from litestar.plugins import RedisPlugin
from litestar.middleware import RateLimitMiddleware
import msgspec

class User(msgspec.Struct):  # 2x faster than Pydantic
    id: int
    name: str

redis_plugin = RedisPlugin(connection_string="redis://localhost")

@get("/users/{user_id}")
async def get_user(user_id: int, redis: Redis = Provide[redis_plugin]) -> User:
    cached = await redis.get(f"user:{user_id}")
    if cached: return msgspec.json.decode(cached)
    user = await db.fetch_user(user_id)  # Auto-serialized
    await redis.setex(f"user:{user_id}", 300, msgspec.json.encode(user))
    return user

app = Litestar(
    route_handlers=[get_user],
    plugins=[redis_plugin],
    middleware=[RateLimitMiddleware("100/minute")],
    openapi_config={"title": "Enterprise API", "version": "3.1.0"}
