Set up this registry in the Cargo configuration file (for example ~/.cargo/config.toml):

[registry]
default = "gitea"

[registries.gitea]
index = "sparse+" # Sparse index
# index = "" # Git

[net]
git-fetch-with-cli = true

To install the package using Cargo, run the following command:

cargo add runtime-function@0.2.6

Pure Function Runtime System - Deterministic DAG-based data transformations

Pure Function Runtime System

A high-performance, deterministic execution engine for DAG-based data transformations. Define complex logic as JSON-serialized graphs and execute them with built-in safety, gas metering, and zero-copy data passing.

Features

Deterministic — Same inputs + context always produce identical outputs
Zero-Copy — Arc and CoW for efficient data passing between nodes
Financial Grade — 128-bit fixed-point decimal math (rust_decimal)
Sandboxed — ES5-subset expressions with no host access
Gas Metered — Prevents CPU exhaustion via granular resource limits
Multi-Language — Native Rust, Node.js (napi-rs), Go (CGO) bindings

Quick Start

Rust

[dependencies]
runtime-function = { version = "0.2", registry = "madapes" }

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

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

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