Comment (by debily):

 Replying to [comment:4 isis]:

 What we really need eventually is a way for the ''same'' random fuzzer
 input to be sent to both a C function and a Rust function, both of which
 are supposed to behave identically (e.g. the parsers in
 `src/or/protover.c` and `src/rust/protover/protover.rs`).

 Well I could do a json dump of structures and compare them, though one can
 never be sure of correctness of used json libraries.
