1//! # Shared connection support for backends
2//!
3//! The [`MakeShared`] trait defines how to create shared backend instances, potentially with configuration options.
4//! This allows for flexible and reusable backend implementations that can be easily integrated into different parts of an application.
5//!
6//! ## Features:
7//! - `MakeShared` trait: Defines methods for creating shared backend instances, with or without configuration.
8//! - Support for various backend types, enabling code reuse and consistency across workers.
9//! - Performance optimizations by allowing backends to reuse connections and resources.
