Bridgerust: One Rust Core, Every Ecosystem

Source: Dev.to

Introduction

Write high‑performance infrastructure libraries for Python, Node.js, and other ecosystems, powered by a shared Rust core.
BridgeRust lets you write your library once in Rust and automatically generate native, high‑performance bindings for multiple languages.

How BridgeRust Works

BridgeRust is a unified framework that provides:

• Project scaffold – set up a multi‑language project in seconds.
• Unified macro system – a single #[export] macro works for all target languages.
• Type conversions – automatic mapping of Vec, Option, Result, and more.
• Building & publishing – integrated CLI to build wheels and npm packages.

Getting Started

Project initialization

bridge init my-awesome-lib
cd my-awesome-lib

Writing exported functions

// src/lib.rs
use bridgerust::export;

#[export]
pub fn greet(name: String) -> String {
    format!("Hello, {}! This is logic from Rust.", name)
}

#[export]
pub struct Point {
    pub x: f64,
    pub y: f64,
}

#[export]
pub fn fast_math(points: Vec) -> f64 {
    // Heavy computation here...
    points.iter().map(|p| p.x + p.y).sum()
}

Building packages

bridge build --all

The command generates:

• A Python wheel (pip install …)
• A Node.js native addon (npm install …)

Example Usage

Python

import my_awesome_lib

print(my_awesome_lib.greet("Pythoneer"))

p1 = my_awesome_lib.Point(1.0, 2.0)
result = my_awesome_lib.fast_math([p1])

Node.js

const lib = require("my-awesome-lib");

console.log(lib.greet("JavaScripter"));

const p1 = new lib.Point(1.0, 2.0);
const result = lib.fastMath([p1]); // fast_math → fastMath automatically

Real‑World Example: Embex

We built Embex, a universal vector‑database client, with BridgeRust. It supports Pinecone, Qdrant, LanceDB, and more, while maintaining a single Rust codebase for core logic (connection pooling, retry strategies, SIMD operations).

• Python package: pip install embex
• Node.js package: npm install @bridgerust/embex

Key Benefits

• Zero boilerplate – no manual PyModule or napi_register_module definitions.
• Performance – zero‑cost abstractions keep your code running at native Rust speed.
• Developer experience – the CLI streamlines the entire lifecycle from init to publish.
• Consistency – Python and JavaScript users receive identical features and bug fixes simultaneously.

Getting the CLI and Resources

  cargo install bridge
