receipt-bench

Replayable benchmark substrate for Rust projects. Captures structured receipts timestamped and keyed to commit hash + machine fingerprint, enabling diffs between runs.

Crates

• BenchmarkSuite — semantic search, compression round-trip, memory lookups
• BenchmarkReceipt — provenance receipt (timestamp, commit hash, machine fingerprint)
• ReceiptDiff — comparison utility between benchmark receipts

Usage

use receipt_bench::{BenchmarkSuite, BenchmarkReceipt, MachineFingerprint};

let suite = BenchmarkSuite::new();
let receipt = suite.run()?;
println!("{:?}", receipt);

Design Goals

• Local-first: no network, no external services
• Minimal dependencies: serde, thiserror, chrono, sha2
• MSRV 1.75, Rust 2021 edition
• No unwrap() in production code
