Generic serialization/deserialization support corresponding to the
`derive(RustcEncodable, RustcDecodable)` mode in the compiler. Also includes
support for hex, base64, and json encoding and decoding.
This crate is deprecated in favor of serde.
Compared to the original rustc-serialize, this crate:
* Supports all `rustc` targets.
* Can work in `no_std` environments with the `alloc` crate.
