Oh, I'm just curious, are you trying to use honggfuzz-rs with tikv?
I forked tikv a few weeks ago to add honggfuzz-rs to this project but I didn't finish ;-)

@PaulGrandperrin Yes! :P I'm working on this PR: tikv/tikv#3848. The framework is adapted from https://github.com/rust-fuzz/targets (but will run on our own testing infra). Currently the main blocking stone of using honggfuzz is that, TiKV as a library is too large :( But, it's fine to introduce the framework as the first step!

As a workaround for this, you check for new files matching ./hfuzz_workspace/"$fuzz_target"/*.fuzz to judge if something crashed.
