Tower

Tower provides composable services and layers that can be mixed and matched, enabling code reuse across different networking projects, as emphasized in its modular components design.

It's protocol-agnostic, working with any request/response pattern, allowing adaptation to protocols like HTTP or gRPC without being locked into one, as per its overview.

Built around the `async fn(Request) -> Result<Response, Error>` pattern, ensuring consistent error management throughout the service stack, highlighted in the robust error handling feature.

Supports middleware and service layers for flexible design, making it easy to add functionality like logging or authentication in a composable way, as described in the layered architecture.
