一般我们只要对结构体标记 Serialize, Deserialize 特征后,这个结构体就可以支持序列化和反序列化; #[derive(Serialize, Deserialize, Debug)] struct Animal { age: i64, name: String } // 普通转换 #[test] fn test_general() { let json_str = r#" { "
name:String, }#[derive(Serialize, Deserialize)]structMsg<'a> { id:String, person: Cow<'a, Person>, }fnmain() {letperson= Person { id:"123".to_string(), name:"Alice".to_string(), };letmsg= Msg { id:"456".to_string(), person: Cow::Borrowed(&person), };letmsg_str= serd...

#[derive(Serialize, Deserialize)] struct Person { name: String, age: u32, address: String, } 创建一个Person对象,并使用serde的to_string函数将其序列化为Rust文本: 代码语言:txt 复制 fn main() -> Result<()> { let person = Person { name: "John".to_string(), age: 30, address:...

#[derive(Debug, Serialize, Deserialize)]struct Message { message: String,}1.2.3.4.5.6.7.现在您可以为端点定义处理程序（handler）函数。在处理程序函数的顶部，您可以为自定义行为添加装饰符：复制 #[get("/")]async fn hello() -> impl Responder { HttpResponse::Ok().json(Message { ...
在这个方法中你需要执行visitor.visit_string(String),这里参数String为字段名。由于我的目的是返回一个T实例,因此这里我只要将Deserializer::deserialize_struct()获得的字段名依序传给visitor.visit_string即可(上图没有示例,请自行实现);然后又回到next_key_seed()调用seed.deserialize(&mut *)处;...
