CKM Core — the Single Source of Truth for all CKM language SDKs.

This crate contains ALL CKM algorithms: types, engine, migration, validation, and formatting. It has zero FFI concerns. Language wrappers (napi-rs, PyO3, CGo) depend on this crate.

Quick Start

use ckm::CkmEngine;
use serde_json::json;

let data = json!({
    "$schema": "https://ckm.dev/schemas/v2.json",
    "version": "2.0.0",
    "meta": {
        "project": "my-tool",
        "language": "rust",
        "generator": "hand-authored",
        "generated": "2026-01-01T00:00:00.000Z"
    },
    "concepts": [],
    "operations": [],
    "constraints": [],
    "workflows": [],
    "configSchema": []
});

let engine = CkmEngine::new(data);
let index = engine.topic_index("my-tool");
println!("{}", index);
