WR-Schemas
wr-schemas的Python项目详细描述
模式描述：
- a data structure
- a mapping of one data structure into another
架构由字段列表组成。
字段没有类型-在某种程度上，它本身就是一个类型。字段不是类型，而是双向的 地图绘制。给定两个不同的数据结构x和y，映射描述如何从 y.f以及如何从x.f计算y.f。
字段支持以下属性：
- name
- mapping
- default
- source_name (source_names)
- min_len, max_len, auto_trim
- min, max
- choices
- regex
- required, forbidden
- nullable
另外：
- Nested fields are supported.
- Fields are easy to clone for reuse.
- Fields and schemas are easy to reverse.
- Schemas are easy to chain.
