<div align="center"> <h1><code>cargo fuzz</code></h1> <p><b>A <code>cargo</code> subcommand for fuzzing with <code>libFuzzer</code>! Easy to use!</b></p> </div>Installation
$ cargo install cargo-fuzz
Note: libFuzzer needs LLVM sanitizer support, so this only works on x86-64 and Aarch64,
and only on Unix-like operating systems (not Windows). You'll also need a C++ compiler with C++11 support.
Usage
cargo fuzz init
Initialize a cargo fuzz project for your crate!
If your crate uses cargo workspaces, add fuzz directory to workspace.members in root Cargo.toml
fuzz directory can be either a part of an existing workspace (default)
or use an independent workspace. If latter is desired, you can use
cargo fuzz init --fuzzing-workspace=true.
cargo fuzz add <target>
Create a new fuzzing target!
cargo fuzz run <target>
Run a fuzzing target and find bugs!
cargo fuzz fmt <target> <input>
Print the std::fmt::Debug output for a test case. Useful when your fuzz target
takes an Arbitrary input!
cargo fuzz tmin <target> <input>
Found a failing input? Minify it to the smallest input that causes that failure for easier debugging!
cargo fuzz cmin <target>
Minify your corpus of input files!
cargo fuzz coverage <target>
Generate coverage information on the fuzzed program!
Documentation
Documentation can be found in the Rust Fuzz Book.
You can also always find the full command-line options that are available with
--help:
$ cargo fuzz --help
Trophy case
The trophy case has a list of bugs
found by cargo fuzz (and others). Did cargo fuzz and libFuzzer find a bug
for you? Add it to the trophy case!
