Fuzzing

Prost ships a few fuzz tests, using both libfuzzer and aflfuzz.

afl

To run the afl fuzz tests, first install cargo-afl:

cargo install -f afl

Then build a fuzz target and run afl on it:

cd fuzz/afl/<target>/
cargo afl build --bin fuzz-target
cargo afl fuzz -i in -o out target/debug/fuzz-target

To reproduce a crash:

cd fuzz/afl/<target>/
cargo build --bin reproduce
cargo run --bin reproduce -- out/crashes/<crashfile>
