Rust

The core itself. run_case and run_suite are the typed entry points; Benchmark::command_json is the same surface the other nine bindings forward verbatim.

cargo add benchmark-core

use benchmark_core::{run_case, BenchmarkCase, load_candles};
use std::path::Path;

let case = BenchmarkCase::from_json(&std::fs::read_to_string("cases/sma-crossover-01.json")?)?;
let data = load_candles(Path::new("datasets").join(&case.dataset_ref).as_path())?;

let result = run_case(&case, &data)?;
println!("{} passed={} hash_match={}", result.id, result.passed, result.hash_match);

The command surface

Every binding exposes the same four commands and returns the core's canonical JSON string verbatim. That is what makes byte equality the cross-language check.

cmd	Payload	Response
run_case	{case, data}	a CaseResult — passed, hash_match, hash, recomputed
run_suite	{suite, datasets}	a SuiteReport — the results sorted by id, plus the tally
list_cases	{suite}	{"ids": [...]}, sorted
version	—	{"version": ..., "engine_version": ...}

A domain error — a malformed case, an unknown command — comes back in-band as {"ok":false,"error":...} rather than as an exception.

One committed example of every envelope lives in golden/commands/, with the exact response each must produce beside it in golden/expected/.
