Rust

A safe Rust abstraction layer for native Node.js modules.

Travis Build Status Appveyor Build Status npm

Rust bindings for writing safe and fast native Node.js modules.

Getting started

Once you have the platform dependencies installed, getting started is as simple as:

$ npm install -g neon-cli
$ neon new my-project

See the Getting Started guide for details.

Platform Support

Operating Systems

Linux macOS Windows

Node.js

Node 4 Node 6 Node 7 Node 8

Support for LTS versions of Node and current are expected. If you're using a different version of Node and believe it should be supported, let us know.

Rust

Neon supports Rust stable version 1.18 and higher. We test on the latest stable, beta, and nightly versions of Rust.

A Taste...

A Neon function takes a Call object and produces a Rust Result that's either a JS value or the Throw constant (meaning a JS exception was thrown). The Call object provides access to a memory management scope, which safely manages the rooting of handles to heap objects:

fn make_an_array(call: Call) -> JsResult<JsArray> {
    let scope = call.scope; // the current scope for rooting handles
    let array: Handle<JsArray> = JsArray::new(scope, 3);
    array.set(0, JsNumber::new(scope, 9000))?;
    array.set(1, JsNumber::new(scope))?;
    array.set(2, JsNumber::new(scope, 3.14159))?;
    Ok(array)
}
