.fuzz_target!
macro would sometimes expand to versions of itself that were not $crate
prefixed and would result in “error: cannot find macro fuzz_target
in this scope” if the caller didn't import the macro but used the qualified version of it instead.Released 2020-05-26.
cargo fuzz
is requesting the std::fmt::Debug
output of an input or not. This is always false during regular fuzzing, so making this check faster should give slightly better fuzzing throughput.Released 2020-05-13.

Upgraded libfuzzer to commit 4a4cafa.
Notably, this pulls in the new Entropic engine for libFuzzer, which should boost fuzzing efficiency when enabled. You can enable Entropic by passing -entropic=1
to your built fuzz targets (although, note that it is still labeled “experimental”).

Arbitrary
implementation could fail to construct an instance of itself because the fuzzer provided too few bytes. See https://github.com/rust-fuzz/libfuzzer/issues/59 for details.Released 2019-01-22.

CUSTOM_LIBFUZZER_STD_CXX=<lib>
environment variable during builds that already use a custom libFuzzer checkout with CUSTOM_LIBFUZZER_PATH
. This allows you to explicitly choose to link LLVM or GNU C++ standard libraries.Released 2020-01-14.
arbitrary
0.3.x now. It is re-exported as libfuzzer_sys::arbitrary
.#[derive(Arbitrary)]
with the "arbitrary-derive"
cargo feature. This is a synonym for the arbitrary
crate's "derive"
cargo feature.
