//! # What are these tests?
//!
//! These tests ensure that regressions in the unmarshaling code are caught.
//!
//! They check all artifacts of the fuzzer that crashed this lib, and make sure they no longer crash the library.
//!
//! The content of the files is mostly garbage, but it triggers "intersting" behaviour in the unmarshaling code.
//! So if your change fails one of these tests you probably made an error somwhere.
//!
//! Sadly these tests cannot really tell you where your error is specifically outside the standard backtrace rust will provide to you. Sorry.
