Pure Function Runtime System - Deterministic DAG-based data transformations

Pure Function Runtime System

runtime-function is a high-performance, deterministic execution engine for DAG-based data transformations. It allows you to define complex logic as JSON-serialized graphs and execute them with built-in safety, gas metering, and zero-copy data passing.

Features

Language Support: Native Rust, Node.js (via napi-rs), and Go (via CGO).
Deterministic: Same inputs + context always produce identical outputs.
Gas Metered: Prevents CPU exhaustion via granular resource limits.
Zero-Copy: Uses Arc and CoW for efficient data handling.
Financial Grade: 128-bit fixed-point decimal math.

Installation & Usage

Rust

[dependencies]
runtime-function = { git = "https://git.madapes.com/madapes/runtime-function.git" }

use runtime_function::{Engine, Program, Context, Value};

let engine = Engine::new();
let program: Program = serde_json::from_str(json_program)?;
let result = engine.execute(&program, inputs, Context::now());

Node.js

npm install @madapes/runtime-function

import { RuntimeEngine } from '@madapes/runtime-function';

const engine = new RuntimeEngine();
const result = engine.execute(JSON.stringify(program), JSON.stringify(inputs));
console.log(JSON.parse(result));

Go

go get github.com/madapes/runtime-function/bindings/go

import "github.com/madapes/runtime-function/bindings/go"

engine := runtimefunction.NewEngine()
program, _ := runtimefunction.ParseProgram(jsonStr)
result, _ := engine.Execute(program, inputs, nil)

Development

Prerequisites

Rust (latest stable)
Node.js (v18+)
Go (v1.21+)

Building Bindings

# Node.js
cd bindings/nodejs && npm install && npm run build:debug

# Go (requires Rust library build with ffi feature)
cargo build --features ffi
cd bindings/go && go test -v .
