Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

fuzzing

Throwing huge numbers of random, broken inputs at code to find crashes.

Fuzzing runs a target function on generated inputs guided by coverage, looking for panics, hangs, and undefined behavior; cargo-fuzz uses libFuzzer and currently needs nightly.

Examples

  • cargo +nightly fuzz run parse_amount feeds generated bytes to a fuzz_target! and saves any input that crashes it under fuzz/artifacts/parse_amount/.
