1//! This crate provides Serde's two derive macros.
2//!
3//! ```edition2021
4//! # use serde_derive::{Deserialize, Serialize};
5//! #
6//! #[derive(Serialize, Deserialize)]
7//! # struct S;
8//! #
9//! # fn main() {}
10//! ```
11//!
12//! Please refer to [https://serde.rs/derive.html] for how to set this up.
