How to decode JSON object with Rust keyword attribute name?

Question

I was wondering if it is possible to decode a JSON object in Rust that has an attribute name which is also a Rust keyword. I am working with the rustc-serialize crate and my struct definition looks like this:

#[derive(RustcDecodable)]
struct MyObj {
  type: String
}

The compiler throws an error because type is a keyword. The exact compiler error message is:

error: expected identifier, found keyword `type`
src/mysrc.rs:23     type: String,
                           ^~~~

Sorry for the rookie question, I have just started trying out Rust.

You can use the serde crate. It supports renaming of fields since February 2015

Your example could then look like this:

#[derive(Deserialize)]
struct MyObj {
    #[serde(rename = "type")] 
    type_name: String
}
