Rust Ecosystem

Rust serialization is dominated by the serde data model: libraries implement Serialize/Deserialize once, then plug in format backends.

Benchmark harness

• Directory: rust/ (repository root)
• Output: logs/rust/benchmark-log.csv (Language=rust, times in nanoseconds)
• Runner: rust/scripts/run-benchmarks.sh {smoke|all-single|full|research}

Design choices

1. Prepare outside the loop — fixtures built once with seed 42.
2. Optimal APIs — to_vec/from_slice style; no pretty-print; named MessagePack maps via to_vec_named.
3. Dual mode — bytes and stream (stream currently uses the same buffer path; extend with Write/Read adapters per crate for stricter stream realism).
4. ObjectGraph — skipped (most serde formats do not support cycles without extensions).
