Pros
- +类型安全和自动验证：基于 Python 类型提示实现强类型数据验证，在运行时自动检查数据类型和约束，减少程序错误
- +高性能和可扩展性：V2 版本经过完全重写，提供卓越的性能表现，能够处理大规模数据验证任务
- +优秀的开发体验：与 IDE、linters 和类型检查器无缝集成，提供智能代码补全和错误提示，显著提升开发效率
Cons
- -学习曲线：对于初学者来说，掌握类型提示、模型定义和复杂验证规则需要一定时间
- -版本迁移成本：从 V1 升级到 V2 存在一些破坏性变更，大型项目迁移需要仔细规划
- -依赖开销：作为额外依赖会增加项目的体积，对于简单的数据验证需求可能显得过重
Use Cases
