-Library to serialize and deserialize [Syn] syntax trees.
-
-[**Documentation**][docs-url]
-
-## Usage
-
-Add this to your `Cargo.toml`:
-
-```toml
-[dependencies]
-syn-serde = "0.2"
-```
-
-The current syn-serde requires Rust 1.31 or later.
-
-## Examples
-
-```toml
-[dependencies]
-syn-serde = { version = "0.2", features = ["json"] }
-syn = { version = "1", features = ["full"] }
-```
-
-```rust
-use syn_serde::json;
-
-let syn_file: syn::File = syn::parse_quote! {
-    fn main() {
-        println!("Hello, world!");
-    }
-};
-
-println!("{}", json::to_string_pretty(&syn_file));
-```
-
-This prints the following JSON:
-
-```json
-{
-  "items": [
-    {
-      "fn": {
-        "ident": "main",
-        "inputs": [],
-        "output": null,
-        "stmts": [
-          {
-            "semi": {
-              "macro": {
-                "path": {
-                  "segments": [
-                    {
-                      "ident": "println"
-                    }
-                  ]
-                },
-                "delimiter": "paren",
-                "tokens": [
-                  {

-                  }
-                ]
-              }
-            }
-          }
-        ]
-      }
-    }

-
-### Rust source file -> JSON representation of the syntax tree
-
-The [`rust2json`] example parse a Rust source file into a `syn_serde::File`
-and print out a JSON representation of the syntax tree.
-
-[`rust2json`]: examples/rust2json
-
-### JSON file -> Rust syntax tree
-
-The [`json2rust`] example parse a JSON file into a `syn_serde::File` and
-print out a Rust syntax tree.
-
-[`json2rust`]: examples/json2rust
-
-## Optional features
-
-* **`json`** — Provides functions for JSON <-> Rust serializing and
-  deserializing.
-
-## Relationship to Syn
-
-syn-serde is a fork of [Syn], and syn-serde provides a set of data structures
-similar but not identical to [Syn]. All data structures provided by syn-serde
-can be converted to the data structures of [Syn] and [proc-macro2].
-
-The data structures of syn-serde 0.2 is compatible with the data structures of [Syn] 1.0.

-# syn_serde_codegen
-
-This is an internal (not published on crates.io) crate which is used to generate
-the files in the `gen/` directory of `syn-serde`. It is used to ensure that the
-implementations for `Syn` remain in sync with the
-actual AST.
-
-To run this program, run `cargo run` in this directory, and the `gen/` folder
-will be re-generated.
-
-This program is slow, and is therefore not run when building `syn-serde` as part of
-the build script to save on compile time.

-//! Library to serialize and deserialize [Syn] syntax trees.
-//!
-//! ## Examples
-//!
-//! ```toml
-//! [dependencies]
-//! syn-serde = { version = "0.2", features = ["json"] }
-//! syn = { version = "1", features = ["full"] }
-//! ```
-//!
-//! ```rust
-//! # #[cfg(feature = "json")]
-//! # fn dox() -> Result<(), Box<dyn std::error::Error>> {
-//! use syn_serde::json;
-//!
-//! let syn_file: syn::File = syn::parse_quote! {
-//!     fn main() {
-//!         println!("Hello, world!");
-//!     }
-//! };
-//! println!("{}", json::to_string_pretty(&syn_file));
-//! # Ok(())
-//! # }
-//! ```
-//!
-//! This prints the following JSON:
-//!
-//! ```json
-//! {
-//!   "items": [
-//!     {
-//!       "fn": {
-//!         "ident": "main",

-//!
-//! ### Rust source file -> JSON representation of the syntax tree
-//!
-//! The [`rust2json`] example parse a Rust source file into a `syn_serde::File`
-//! and print out a JSON representation of the syntax tree.
-//!
-//! ### JSON file -> Rust syntax tree
-//!
-//! The [`json2rust`] example parse a JSON file into a `syn_serde::File` and
-//! print out a Rust syntax tree.
-//!
-//! ## Optional features
-//!
-//! - **`json`** — Provides functions for JSON <-> Rust serializing and
-//!   deserializing.
