Crate dev_fuzz 

dev-fuzz

Fuzzing harness integration for Rust. Wraps cargo-fuzz (libFuzzer-based) and emits findings as dev_report::Report.

Captures crashes, timeouts, and OOM events with reproducer inputs attached as Evidence::FileRef so consumers can replay the input that triggered each finding.

Quick example

use dev_fuzz::{FuzzBudget, FuzzRun};
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();

Requirements

cargo install cargo-fuzz
rustup toolchain install nightly      # libFuzzer requires nightly

The crate detects absence of either prerequisite and surfaces FuzzError::ToolNotInstalled / FuzzError::NightlyRequired without panicking.
