Rust WASM 编程 #
1. 初始化项目 #
cargo new hello-wasm
cd hello-wasm
2. 安装 wasm-pack #
cargo install wasm-pack
3. 编写代码 #
编辑 src/main.rs 文件：
// 使用 wasm-bindgen 在 Rust 与 JavaScript 之间通信
extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;
#[wasm_bindgen]
extern {
pub fn alert(s: &str);
}
#[wasm_bindgen]
pub fn greet(name: &str){
alert(&format!("Hello, {}!",name));
}
编辑 Cargo.toml 文件：
[package]
name = "hello-wasm"
version = "0.1.0"
edition = "2021"
authors = ["Pone Ding <[email protected]>"]
description = "A sample project with wasm-pack"
license = "MIT/Apache-2.0"
repository = "https://github.com/poneding/hello-wasm"
[lib]
crate-type = ["cdylib"]
[dependencies]
wasm-bindgen = "0.2"
4. 构建项目 #
wasm-pack build --scope [npm-username]
