rust-fuzz/libfuzzer (libfuzzer-sys)

v0.4.9

Compare Source

Released 2025-01-28.

Added

• The example_init demonstrates how to pass an initialization code block to
  the fuzz_target! macro.

Changed

• The fuzz_target! macro now supports the generation of LLVMFuzzerInitialize
  to execute initialization code once before running the fuzzer. This change is
  not breaking and is completely backward compatible.
