serde: Enable the “rc” feature This allows us to serialize and deserialize fields containing “Rc” and “Arc” types. I need this for testing PDL, but it could potentially be useful for others as well. Note that enabling the feature simply allows Serde to generate code in cases where it would fail with an error before. Test: presubmit (cherry picked from https://android-review.googlesource.com/q/commit:1fbe19a54c5d251ff0eff9b3c5cd4ce0bf093cee) Merged-In: Ie39d6b842c1718f0f2c4f824388a324df271804e Change-Id: Ie39d6b842c1718f0f2c4f824388a324df271804e
Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.
You may be looking for:
#[derive(Serialize, Deserialize)][dependencies] # The core APIs, including the Serialize and Deserialize traits. Always # required when using Serde. The "derive" feature is only required when # using #[derive(Serialize, Deserialize)] to make Serde work with structs # and enums defined in your crate. serde = { version = "1.0", features = ["derive"] } # Each data format lives in its own crate; the sample code below uses JSON # but you may be using a different one. serde_json = "1.0"
use serde::{Serialize, Deserialize}; #[derive(Serialize, Deserialize, Debug)] struct Point { x: i32, y: i32, } fn main() { let point = Point { x: 1, y: 2 }; // Convert the Point to a JSON string. let serialized = serde_json::to_string(&point).unwrap(); // Prints serialized = {"x":1,"y":2} println!("serialized = {}", serialized); // Convert the JSON string back to a Point. let deserialized: Point = serde_json::from_str(&serialized).unwrap(); // Prints deserialized = Point { x: 1, y: 2 } println!("deserialized = {:?}", deserialized); }
Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.
