serde序列化反序列化

本文主要是介绍serde序列化反序列化，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

导入Crate

serde_json = {version = "1.0"}
serde = {version = "*", features = ["derive"]}

代码中使用

extern crate serde;
extern crate serde_json;use serde::{Serialize, Deserialize};#[derive(Serialize, Deserialize)]
struct Person{name: String,age: u8,phones: Vec<String>,
}//从json中反序列化对象let data = r#"{"name": "John Doe","age": 43,"phones": ["18800010002","18800010003"]}"#;let p: Person = serde_json::from_str(data)?;println!("{}", p.name);
//序列化对象为jsonlet json = serde_json::to_string(&p)?;println!("序列化结果：{}", json);
//硬编码json对象let full_name = "henreash";let age_last_year = 42;let henreash = json!({"name": full_name,"age": age_last_year + 1,"phone": ["+86-10000","+86-10001",]});let json = henreash.to_string();println!("{}", json);

这篇关于serde序列化反序列化的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
