Is there an equivalent of `afl-clang-fast` in `libfuzzer-sys` for instrumenting my own fuzzer?

Is there an equivalent of `afl-clang-fast` within `libfuzzer-sys`?

```
afl-clang-fast test.c -o test
```

I would like to develop my own fuzzer and utilize `libfuzzer-sys` solely for instrumentation.
