Crate dev_fuzz 

dev-fuzz

Fuzzing harness integration for Rust. Part of the dev-* verification suite.

Wraps cargo-fuzz (libFuzzer-based) and emits findings as dev-report::Report. Captures crashes, timeouts, and OOM events with reproducer inputs attached.

What is fuzzing?

Fuzzing feeds random or guided-random inputs to your code looking for crashes, panics, or unexpected behavior. It’s especially valuable for parsers, deserializers, network protocol handlers, and anything that touches untrusted input.

Quick example

use dev_fuzz::{FuzzRun, FuzzBudget};
use std::time::Duration;

let run = FuzzRun::new("parse_input", "0.1.0")
    .budget(FuzzBudget::time(Duration::from_secs(60)));
let result = run.execute().unwrap();
let report = result.into_report();

Status

Pre-1.0. API shape defined; subprocess integration lands in 0.9.1.
