Spans in the AST returned by `parse_item_from_source_str` and other parsing functions contain byte offsets into the source code they were parsed from. The pretty printer uses these Spans [here][1] to preserve the representation of literals when parsing and printing back out unmodified. In this bug, the byte offset of a string in the input to `parse_item_from_source_str` coincidentally matched the byte offset of a totally different string in the input to `parse_crate_from_file` called [here][2] by Syntex. The Span from the former triggered the pretty printer to write out the content of the latter. By using the same ParseSess, Spans from the two `parse_*` calls never collide.

Serde
Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.

Serde in action
#![feature(proc_macro)]
#[macro_use]
extern crate serde_derive;
extern crate serde_json;
#[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);
}
Getting help
Serde developers live in the #serde channel on
irc.mozilla.org
. The #rust channel is also a
good resource with generally faster response time but less specific knowledge
about Serde. If IRC is not your thing, we are happy to respond to GitHub
issues as well.
