node-rust-jit

node.JS run Rust language Just In Time

Installation

You can install with npm:

$ npm install rust-jit

Prepare

npm install -g neon-cli

You will also need to install:

On Unix

• Rust
• make
• A proper C/C++ compiler toolchain, like GCC

On Mac OS X

• Rust
• Xcode
  • You also need to install the Command Line Tools via Xcode. You can find this under the menu Xcode -> Preferences -> Downloads
  • This step will install gcc and the related toolchain containing make

On Windows

Option 1

Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

Option 2

Install tools and configuration manually:

• Visual C++ Build Environment:

  • Option 1: Install Visual C++ Build Tools using the Default Install option.

  • Option 2: Install Visual Studio 2015 and select Common Tools for Visual C++ during setup. This also works with the free Community and Express for Desktop editions.

  • Option 3: if you already have Visual Studio 2015 installed and did not install the Common Tools for Visual C++ during setup, you can File -> New -> Project, pick any of the options under Templates -> Other Languages -> Visual C++ then Ok and Visual Studio will offer to install the Common Tools for Visual C++ with a "Install Missing Features" / "You need the Universal Windows App Development Tools to develop Windows app projects." dialog.

  :bulb: [Windows Vista / 7 only] requires .NET Framework 4.5.1

• Install Rust

• Launch cmd, npm config set msvs_version 2015

If the above steps didn't work for you, please visit Microsoft's Node.js Guidelines for Windows for additional tips.

How to Use

notice:The compilation is to be put in the startup file of node.js because it is time consuming

example

const RustJit = require("rust-jit");
const path = require("path");

let rustJit  = new RustJit();

let code = `
    let scope = call.scope;
    let option_num = call.arguments.get(scope,0);
    let mut num:i32 = 0;
    if let Some(x1) = option_num {
        if let neon::js::Variant::Integer(x2) = x1.variant() {
            num = x2.value() as i32;
        }
    }
    let mut fibnum:i32 = 1;
    if num>2 {
        let mut a:i32 = 1;
        let mut b:i32 = 1;
        let mut c:i32 = 0;
        for _i in 2..num {
            c=a+b;
            a=b;
            b=c;
        }
        fibnum = c;
    }
    
    Ok(neon::js::JsInteger::new(scope, fibnum))
`;
let rustFibByCode = rustJit.compileSync(code,'JsInteger');
console.log("rustJit.compileSync fib(5)=>5:"+rustFibByCode(5));

let rustFibByFile = rustJit.compileByFileSync(path.join(__dirname,"test.rs"),'JsInteger');
console.log("rustJit.compileByFileSync fib(6)=>8:"+rustFibByFile(6));
