JSON/YAML/TOMLIniXML
Rust中序列化用的最多的是 serde, 依赖它有很多出色的第三方库可以使用。
其中serde本身支持JSON/YAML/TOML/JSON5…多种这里使用serde_json.
XML需要第三方库quick-xml他通过支持serde也支持了结构体序列化配合十分完美.
INI比较特别这里有一个比较强大的库支持带注释的ini, configparser.
依赖文件:
[dependencies]
configparser * # ini支持
serde { version *, features [derive] } # 后续的库的基础
serde_json * # JSON支持
quick-xml { version *,features[serde,serialize] } # xml 支持Code
