Module upstream 

Upstream service abstraction.

This module provides the Upstream trait for calling backend services when cache misses occur.

Overview

The Upstream trait abstracts over any async service that can handle requests and return responses. This allows the caching layer to be agnostic to the actual service implementation.

Framework Integration

Protocol-specific crates provide implementations for common frameworks:

• hitbox-reqwest - Reqwest HTTP client integration
• hitbox-tower - Tower service integration
