> Rust-only: it doesn't sacrifice simplicity and performance for cross-language compatibility

A serialization format for one language only? That's pretty rich.

Python's Pickle, java.io.Serializable, Ruby's marshal, plenty of examples of this, though pretty much all of them come with the caveat that they are _not_ for untrusted data sources, or even really data sources other than the application that produced them in the first place.

You can also turn on the `strict` feature for C compatibility, but without any way to get the type definitions into a C header it's kind of pointless.

I'm not interested in adding C compatibility because I don't want to write C, but I also won't go out of my way to impede others who might want to.
