SerDe即序列化和反序列化，JSONSerDe基本思想是使用json.org的JSON库，使用这个库可以读取一行数据并解析...
对比这三种语言,我们可以大致猜到serde和serde_json提供便利的原理。使用了类似于反射的机制来实现的。后面会分析反射和Rust里面使用技术的不同。(一个是运行时,一个是编译期的行为) 在Rust里面,这个技术是proc macro。为了方便理解,实现的原理可以大致理解为,通过proc macro获取结构体的信息,然后生成相应的代码。

然后,你可以在Rocket中使用Serde来处理JSON数据: #[macro_use] extern crate rocket; use serde::{Deserialize, Serialize}; #[derive(Serialize, Deserialize)] struct User { name: String, age: u32, } #[get("/user")] fn get_user() -> String { let user = User { name: "John Doe".to_...
