Rust: Convert a data structure into a JSON string

Mar 24, 2022

We've already done most of the heavy-lifting for turning a structure into JSON:

use serde::{Deserialize, Serialize};
use serde_json;
#[derive(Serialize, Deserialize)]
struct Person {
first_name: String,
last_name: String,
age: u8,
}
fn main() {
let first_name = String::from("Glenn");
let last_name = String::from("Gillen");
let age = 40;
let p = Person{ first_name, last_name, age };
let data = serde_json::to_string(&p).expect("Not a serializable type");
println!("{}", data)
}

Instantiate an instance of our Person, parse it into the serde via calling to_string. Done.

Hi, I'm Glenn! 👋 I've spent most of my career working with or at startups. I'm currently the Director of Product @ Ockam where I'm helping developers build applications and systems that are secure-by-design. It's time we started securely connecting apps, not networks.

Previously I led the Terraform product team @ HashiCorp, where we launched Terraform Cloud and set the stage for a successful IPO. Prior to that I was part of the Startup Team @ AWS, and earlier still an early employee @ Heroku. I've also invested in a couple of dozen early stage startups.
