rust: Factory Method Pattern

geovindu2026-09-18 9:53

一、引言

本节介绍工厂方法模式（Factory Method Pattern）在珠宝制造业务系统中的实际应用背景，说明为什么需要将产品线创建逻辑与业务处理解耦，以及本文将要展示的 Rust 实现思路。

二、核心概念

本节讲解工厂方法模式的核心思想，包括抽象工厂、具体工厂、产品接口与具体产品之间的关系，以及该模式在创建型模式中的定位。

  • 模式定义与结构：说明工厂方法模式的定义、参与者角色以及类图结构。
  • 适用场景：分析在珠宝多产品线（黄金、钻石、彩色宝石、铂金）场景下使用工厂方法模式的原因。
  • 与简单工厂的区别：对比工厂方法模式与简单工厂在扩展性和职责划分上的差异。

三、Rust 实现要点

本节围绕 Rust 语言特性，介绍如何用 trait、泛型和关联常量实现工厂方法模式，并说明错误处理与线程安全设计。

  • trait 抽象设计：讲解 ProductLineFactory 与 ProductLineInfo 两个核心 trait 的设计思路。
  • 泛型与关联常量：说明如何通过泛型参数和关联常量为不同产品线提供静态配置。
  • 错误处理与并发：介绍 JewelryError 统一错误类型以及线程池、消息队列在订单处理中的应用。

四、实战示例

本节给出完整的 Rust 代码示例，展示从领域模型、工厂实现到订单处理服务的完整链路，并演示黄金、钻石、彩色宝石、铂金四条产品线的调用方式。

五、总结

本节总结工厂方法模式在 Rust 珠宝业务系统中的落地效果，回顾模式带来的扩展性收益，并给出后续优化方向。
