Update the serialize_person function to convert a Person instance to Json.
Update the deserialize_person function to convert a Json string to a Person instance.
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize, Debug, PartialEq)]
struct Person {
name: String,
age: u8,
}
fn serialize_person(person: &Person) -> String {
// return a JSON string from the given Person instance
}
fn deserialize_person(json: &str) -> Person {
// return a Person instance from the given JSON string
}
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_serialize() {
let person = Person {
name: "Alice".to_string(),
age: 30,
};
let json = serialize_person(&person);
assert_eq!(json, "{\"name\":\"Alice\",\"age\":30}");
}
#[test]
fn test_deserialize() {
let json = "{\"name\":\"Bob\",\"age\":25}";
let person = deserialize_person(json);
assert_eq!(person, Person {
name: "Bob".to_string(),
age: 25,
});
}
