rustify

Rust WebAssembly transform for Browserify. Because this is an unstable rust feature, at the time of writing it relies on wasm-gc to be available from the command line. See Installation for instructions on how to install. Probably also doesn't work on Windows.

Because this feature is experimental in Rust, this module should be considered similarly.

Usage

owserify -t rustify index.js > bundle.js

ndex.js
rust = require('rustify')

wasm = rust`
no_mangle]
b fn add_one(x: i32) -> i32 {
x + 1



ssembly.instantiate(wasm, {})
hen(function (res) {
var addOne = res.instance.exports.add_one
console.log(addOne(41))
console.log(addOne(68))
.catch(function (e) {
console.error('Creating WASM module failed', e)

External

rust = require('rustify')

wasm = rust('./add-one.rs')

ssembly.instantiate(wasm, {})
hen(function (res) {
var addOne = res.instance.exports.add_one
console.log(addOne(41))
console.log(addOne(68))
.catch(function (e) {
console.error('Creating WASM module failed', e)

API

uint8Array = rust(filename)

Create a valid .rs file to a Uint8Array, ready to be passed to the WASM constructor.

uint8Array = rust#string

Create an inline rust template string to a Uint8Array, ready to be passed to the WASM constructor.

Installation
