useserde::{Serialize, Deserialize};#[derive(Serialize, Deserialize)]enumAnimal{ Dog { name:String, age:u32}, Cat { name:String, age:u32}, } 在序列化和反序列化枚举类型时,需要使用#[serde(tag = "type")]指定枚举类型的标签,例如: use serde_json; let dog = Animal::Dog {name: "Tom"...

1回答 将具有多个元素的JSON字段从String反序列化到Vec<u8>s的Vec 、 将json文件反序列化为以下铁锈结构:struct IpfsConsequence { Ok(s.as_bytes().to_vec())这会编译,我可以编写代码来非常好地使用它。但是在co_authors中使用Vec类型感觉有点混乱。我更喜欢使用Vec型,但我找不到办法做到这一点。 ser...
