It uses https://github.com/rust-fuzz/honggfuzz-rs project to do coverage-based fuzzing. Currently, fuzzing is done only on Linux.

From the current directory, run

nice -n 19 cargo hfuzz run sudachi-fuzz

If there are crashes/panics, it is possible to minimize examples by running

HFUZZ_RUN_ARGS='-M' cargo -vv hfuzz run sudachi-fuzz

To run failures with the debugger, run (need to have lldb installed)

cargo hfuzz run-debug sudachi-fuzz hfuzz_workspace/*/*.fuzz
