资源总共 48MB！这太大了。让我看看 rustc_opt.wasm.br 解压后的大小。

不过，这个体积确实很大。让我重新评估一下：

1. `rustc_opt.wasm.br` - 19MB（brotli 压缩）
2. `wasm32-wasip1.tar.br` - 19MB（brotli 压缩）
3. 其他 JS/WASM - ~10MB

总计 48MB，nginx gzip 后可能更小。

但问题是，解压后的 WASM 文件会更大：
- `rustc_opt.wasm.br` 解压后可能 50-100MB
- `wasm32-wasip1.tar.br` 解压后可能 50-100MB

91MB + 70MB = 161MB 解压后！这太大了，浏览器无法加载。

让我重新考虑这个方案。rubrc 项目确实太大了，不适合离线使用。

让我尝试另一种方案：使用 `rustpython` 的 WASM 版本。但这不是 Rust 编译器。

或者，让我尝试用 `rustc` 的简化版。实际上，有没有一个更小的 Rust 编译器？

让我搜索一下 `mrustc` 的 WASM 版本，或者尝试用 `rustc` 编译一个更小的版本。

实际上，让我重新考虑用户的需求。用户说"支持编译常用rust代码"。这不需要完整的 Rust 编译器。

让我尝试一个完全不同的方案：使用一个简化的 Rust 到 WASM 的编译器。我可以自己写一个简化版的 Rust 编译器（类似之前 C 编译器的方案），但这需要大量工作。

或者，我可以使用 `rust-script` 的 web 版本。

让我搜索一下有没有更小的 Rust 编译器 WASM 项目。

# Rubri - The Rust Browser Interpreter

> [See it in action.](https://garriga.dev/rubri)

Rubri is a proof-of-concept wrapper for [Miri](https://github.com/rust-lang/miri) that runs in the browser.

This allows for extremely fast iterative development, as it avoids compiling the code, which is known to be slow even when done natively.

Execution speed is pretty slow though, probably worse than the `1000x` Miri claims.
Output is especially demanding, a simple loop of 2000 prints takes between 2 and 3 seconds.

The project has been made possible thanks to the work of [bjorn3](https://github.com/bjorn3) on [Cranelift](https://github.com/rust-lang/rustc_codegen_cranelift), [compiling Miri to WASM](https://github.com/rust-lang/miri/issues/722#issuecomment-1960849880) and the [Browser WASI shim](https://github.com/bjorn3/browser_wasi_shim).
All credits are for them, this is just a wrapper I wanted to make to see if Rust could really run in the browser.

## Usage
See the [`index.astro`](./example/src/pages/index.astro) file for an example on how Miri can be used from javascript.
This example has been made with `Vite` or `Astro` in mind, if you don't use any of them you can still run the code by removing the `import.meta.env` directives and adapting the fetch paths.

The [`public/wasm-rustc`](./example/public/wasm-rustc/) folder is needed, as it contains the compiled Miri and the necessary `.rlib` libraries.
You can build your own `wasm-rustc` files by following the instructions in [this issue comment](https://github.com/rust-lang/miri/issues/722#issuecomment-1961278711).

## Limitations
All of them!

Seriously though, this is extremely experimental at the moment.
It doesn't support multiple files, using crates, input/output operations, etc.

Everything not supported by Miri or WASM is not supported by Rubri.

If you have any knowledge on how to improve this, feel free to open a PR!

## How it works
`rustc` is tricky to compile to WASM because linkers are not supported.
Miri though does not need linking, so it can be used to interpret the mid-level intermediate representation Rust uses in its compiling process.

This wrapper loads Miri and the necessary libraries via a Web Worker and invokes it with the provided code.
To improve execution speed, Miri's code has been modified slightly and all checks are disabled (does not check for UB, only runs the code).

rubri 是 Miri（Rust 的解释器）的浏览器包装器，不是完整的编译器。它不需要编译代码，而是直接解释执行。

让我看看 rubri 的资源需求。

rubri 的 zip 文件 108MB！其中 `miri.opt.1718474653.wasm` 就 47MB！这也太大了。

看起来所有 Rust 浏览器编译器/解释器都很大。让我重新考虑。

有没有一个更小的 Rust 编译器/解释器？

让我搜索一下 `rust-script` 或 `cargo` 的简化版本。

实际上，让我考虑另一种方式：使用 `wasmi` 或 `wasmtime` 来运行 Rust 代码。但这不是 Rust 编译器。

或者，我可以尝试用 `rustpython` 的 WASM 版本——但这运行的是 Python 代码。

让我想想还有什么选择...

1. `mrustc` - C++ 写的 Rust 编译器，但编译到 WASM 很复杂
2. `rustc` 官方的 WASM 编译 - 也很大
3. `rubri` / `rubrc` - 已经尝试过了，太大
4. `rustpython` - 是 Python 解释器

让我搜索一下有没有更小的 Rust 编译器项目。

搜索结果没有更合适的 Rust 浏览器编译器项目。

让我重新思考。用户要求的是"Rust WASM 的离线静态网页编译器"。

所有的 Rust 浏览器编译器/解释器都很大（50-100MB+）。这是因为 Rust 编译器本身很复杂。

让我尝试另一种方式：

1. **使用 `rustpython` 的 WASM 版本** - 这是用 Rust 写的 Python 解释器，不是 Rust 编译器
2. **自己写一个简化版的 Rust 编译器** - 类似之前 C 编译器的方案
3. **使用 `wasmer` 或 `wasmtime` 的 Web 版本** - 这些不是 Rust 编译器

让我尝试第2个方案：自己写一个简化版的 Rust 编译器。

但 Rust 语法比 C 复杂得多，包括：
- 所有权和借用
- 生命周期
- 模式匹配
- 泛型
- 特征（trait）

写一个完整的 Rust 编译器需要大量工作。

让我尝试另一种方式：使用一个已经存在的 Rust 到 JavaScript 的转译器。

或者，我可以尝试用 `rustc` 的 `wasm32-unknown-unknown` 目标编译一个简化版的 Rust 编译器。

实际上，让我搜索一下 `rust-script` 或 `cargo-script` 的 web 版本。

rust-script-wasm 是一个个人项目，正在构建自己的 Rust 解释器，不是现成的 Rust 编译器。

让我重新思考。用户要求的是"Rust WASM 的离线静态网页编译器"。

我已经尝试了：
1. `rubrc` - Rust 编译器，但 48MB 压缩，解压后 160MB+，太大
2. `rubri` - Rust 解释器，但 108MB，太大
3. `rust-script-wasm` - 个人项目，不是现成工具

让我尝试一种完全不同的方式：使用 `wasmer` 或 `wasmtime` 的 Web 版本。

或者，我可以尝试用 `rustc` 的 `wasm32-unknown-unknown` 目标编译一个简化版的 Rust 编译器。

实际上，让我尝试另一个方式：使用 `rustc` 的 `cranelift` 后端，编译一个更小的 Rust 编译器。

cranelift 是一个快速的编译器后端，比 LLVM 更轻量。

让我搜索一下 `rustc_codegen_cranelift` 的 WASM 版本。

让我重新思考这个任务。用户要求创建一个 Rust 的离线 WASM 编译器。

我已经尝试了很多现成的项目，但都不合适：
1. `rubrc` - 太大（48MB+）
2. `rubri` - 太大（108MB+）
3. 其他项目 - 不是 Rust 编译器或太小

让我尝试一种完全不同的方式：

**方案 A：自己写一个简化版的 Rust 编译器**

我可以写一个简化版的 Rust 到 WASM 的编译器，支持：
- 变量声明（let, mut）
- 基本类型（i32, i64, f32, f64, bool, string）
- 函数
- 控制流（if/else, while, for）
- 打印输出（println!）
- 基本表达式

这个方案类似于之前 C 编译器的方案，但 Rust 语法更复杂。

**方案 B：使用 `rustpython` 的 WASM 版本**

这是用 Rust 写的 Python 解释器，不是 Rust 编译器。但用户要求的是 Rust 编译器。

**方案 C：使用 `rustc` 的 WASM 编译**

尝试用 rustc 的 `wasm32-wasi` 目标编译一个更小的 Rust 编译器。

让我重新思考用户的需求：
- "支持编译常用rust代码"
- 这意味着需要：变量、函数、控制流、打印

让我尝试方案 A：自己写一个简化版的 Rust 编译器。

但 Rust 的语法非常复杂，特别是：
- 所有权和借用
- 生命周期
- 模式匹配
- 泛型
- 特征

如果用户只需要"常用rust代码"，我可以只支持：
- 基本变量声明
- 函数定义
- 基本控制流
- 打印输出
- 算术表达式

但这仍然是一个编译器，需要：
1. 词法分析器
2. 语法分析器
3. 语义分析器
4. WASM 代码生成器

这是一个非常大的工程。

让我尝试另一种方式：使用 `wasmi` 或 `wasmtime` 的 Web 版本，但这些不是 Rust 编译器。

或者，我可以尝试使用 `rustc` 的 `wasm32` 目标编译一个更小的版本。

实际上，让我想想有没有更简单的方案...

让我尝试使用 `rust-script` 的 WASM 版本。但这不是一个现成的工具。

或者，我可以尝试使用 `cargo` 的 web 版本。

让我再搜索一下 `rust` 的 `web` 编译器。

等等，让我重新考虑 `rubrc` 方案。虽然它很大（48MB），但：
1. 它是完整的 Rust 编译器
2. 它支持标准 Rust 语法
3. 用户可以通过 nginx 下载

48MB 对于现代网络来说不算太大（大约 10-20 秒下载）。

让我尝试配置 `rubrc`，但进行一些优化：
1. 只下载一个 sysroot（wasm32-wasip1）
2. 不下载所有 Monaco 编辑器 worker
3. 简化前端

实际上，让我重新考虑。用户说"优先网上找现成的项目"。我已经找到了 `rubrc`，虽然很大，但它是一个现成的项目。

让我尝试配置 `rubrc` 项目，让它在 nginx 下运行。

关键问题：
1. 需要 COOP/COEP 头部
2. 需要 SharedArrayBuffer
3. 需要修改 JS 文件中的路径

让我先尝试修改路径，然后配置 nginx。

实际上，考虑到体积太大，让我尝试另一种方式：使用 `rustpython` 的 WASM 版本。

但用户要求的是 Rust 编译器，不是 Python 解释器。

好吧，让我尝试用 `rubrc` 但做一些修改。

实际上，让我重新考虑。用户说"常用rust代码"——这意味着：
- 变量声明
- 函数
- 控制流
- 打印

我可以写一个简化版的 Rust 编译器，只支持这些功能。

让我写一个简化版的 Rust 到 WASM 编译器。

这个编译器需要：
1. 词法分析器（Tokenizer）
2. 语法分析器（Parser）
3. 类型检查器（TypeChecker）
4. WASM 代码生成器（CodeGen）

Rust 的语法比 C 复杂，但核心语法（变量、函数、控制流）可以简化。

让我尝试写一个简化版的 Rust 编译器。

**支持的语法：**
- `let x = 5;` / `let mut x = 5;`
- `fn add(a: i32, b: i32) -> i32 { ... }`
- `if/else`
- `while` / `for`
- `println!()`
- 基本表达式

**不支持的语法：**
- 所有权和借用
- 生命周期
- 泛型
- 特征
- 模式匹配
- 枚举
- 结构体（简化版）

这仍然是一个比较大的工程。让我尝试写一个简化版。

实际上，让我再想想。用户说"常用rust代码"。

让我搜索一下有没有 Rust 编译器的 JavaScript 实现。

让我重新思考。现有的 Rust 浏览器编译器都太大了。我需要自己写一个简化版的 Rust 编译器。

这个编译器不需要支持完整的 Rust 语法，只需要支持"常用"功能：
1. 变量声明（let, let mut）
2. 函数定义
3. 基本控制流（if, while, for）
4. 打印输出
5. 基本表达式

让我写一个简化版的 Rust 编译器。

Rust 的核心语法结构：
- `let x = 5;`
- `let mut x = 5;`
- `fn add(a: i32, b: i32) -> i32 { ... }`
- `if condition { ... } else { ... }`
- `while condition { ... }`
- `for i in 0..10 { ... }`
- `println!("hello {}", x);`

编译器结构：
1. Tokenizer - 词法分析
2. Parser - 语法分析，生成 AST
3. TypeChecker - 类型检查
4. CodeGen - 生成 WASM

WASM 部分可以使用之前 C 编译器的基础。

让我开始写这个编译器。

Rust 语法和 C 类似，但有一些不同：
- 变量声明：`let x = 5;` vs `int x = 5;`
- 函数：`fn name() -> type { ... }` vs `int name() { ... }`
- 打印：`println!("hello");` vs `printf("hello\n");`

让我写一个简化版的 Rust 编译器。

这个编译器将：
1. 支持基本类型：i32, i64, f32, f64, bool
2. 支持变量声明和赋值
3. 支持函数定义和调用
4. 支持 if/else
5. 支持 while 循环
6. 支持 for 循环（范围迭代）
7. 支持 println! 宏

让我开始写代码。

# 清理之前失败的 rubrc 下载
rm -rf /shumengya/www/rust-wasm

# 创建 rust-wasm 目录
mkdir -p /shumengya/www/rust-wasm

echo "准备创建 Rust 编译器..."


准备创建 Rust 编译器...


让我写一个简化版的 Rust 编译器。这个编译器将 Rust 代码编译为 WASM，然后在浏览器中执行。

我将使用以下结构：
1. `tokenizer` - 词法分析
2. `parser` - 语法分析
3. `typechecker` - 类型检查
4. `codegen` - WASM 代码生成

让我开始写代码。

Question: Rust compiler WebAssembly browser offline runs in browser WASM rustc


Question: Rust compiler WebAssembly browser offline runs in browser WASM rustc

Running rustc on WASM - compiler - Rust Internals

There is a previous thread wrt how far rustc is to being able to be compiled to WebAssembly, however, the thread hasn't really stated a current state. I was thinking recently about an in-browser playground equivalent, one that runs in WASM, compiles to WASM, and then runs the compiled WASM directly on the browser. Aside from the problem of sandboxing another WASM process like that (monitoring it, and also cutting it off if it runs too long), I find the idea of `rustc.wasm` pretty tantalizing, I see some reddit discussion (1, 2), but no concrete status or pointers. This is the latest status I believe: Compilation to WASM? | Keeping up with WASM developments | 2 | 1391 | March 25, 2019 |. | Moving WebAssembly support forward  compiler | 42 | 8442 | March 25, 2019 |. | How close are we to having rustc.wasm? compiler | 5 | 1703 | March 25, 2019 |.

Can the Rust compiler be compiled to WASM and run on a browser?

Would it be too difficult to compile the Rust compiler to WASM so that it can run on an embedded web view?

Nine Rules for Running Rust in the Browser | Towards Data Science

# Nine Rules for Running Rust in the Browser. Rust Running on the Browser - Source: https://openai.com/dall-e-2/. Do you want your Rust code to run everywhere – from large servers to web pages, robots, and even watches? In this second of three articles [153649d1)52a), 2, 3], I’ll show you how to use WebAssembly (WASM) to run your Rust code directly in the user’s browser. Porting code to WASM in the browser requires several steps and choices, and navigating these can be time-consuming. As with the first article in this series, before we look at the rules one by one, let’s define our terms. For the first prerequisite, see Nine Rules for Running Rust on WASM WASI in *Towards Data Science*. With that move, you will be halfway to running on WASM in the Browser. For the second prerequisite, show that you can create some JavaScript code and run it in a browser.

# WebAssembly on the server: Compiling Rust to WASM and executing it from Go. Server-side WebAssembly: Unifying cross-language logic for high performance and data privacy. WebAssembly on the server: Compiling Rust to WASM and executing it from Go. WebAssembly is often discussed in the web browser context. It’s usually compiled from another language like Go, Rust, or C++, and it gives you a secure sandbox that is often much more performant than executing JavaScript in the browser. Using a runtime library you can host a WebAssembly binary and call it from the host language. It’s the same principle as calling WebAssembly from JS in the browser, except you can do it from Rust or Go or Python. In this post I’ll discuss how we use the same server-side WebAssembly in both our Go server and our JS SDK. The result is that we write our core functionality in Rust and then compile it to WebAssembly.

Rust in WebAssembly | Fermyon Developer

### Spin CNCF. 02Deploy to a Fermyon Service:. Powerful engine for edge apps and functions on Akamai Cloud. Deploy your Spin apps to Fermyon's serverless cloud. Develop and operate Spin apps in your Kubernetes cliuster. # Rust in WebAssembly. but `wasmtime`, Spin, Wagi, and many other WebAssembly tools are written in Rust. Rust can be used to create Fermyon Platform apps. WebAssembly and WASI support are officially supported by the Rust project. To add the `wasm32-wasi` compiler, simply use `rustup`:. Then to compile a program to rust, set the target when running `cargo build`:. `$ cargo build --target wasm32-wasi --release`. WebAssembly binaries will be written to your project’s `target/wasm32-wasi/release` directory. To build a Spin app in rust, use `cargo build`:. The resulting binary can be run in Spin with a `spin.toml` that looks something like this:. command = "cargo build --target wasm32-wasi --release"`. Note: we’ve set the `hello` component’s build command to be the `cargo build` invocation above, so that `spin build` will run it from now on.

Compiling from Rust to WebAssembly - MDN - Mozilla

# Compiling from Rust to WebAssembly. This tutorial shows you how to compile a Rust project into WebAssembly and use it in an existing web app. ## Rust and WebAssembly use cases. There are two main use cases for Rust and WebAssembly:. For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`. This helps compile the code to WebAssembly and produce the right packaging for use in the browser. This creates a new library in a subdirectory named `hello-wasm` with everything you need to get going:.

# A Gentle Introduction to WebAssembly in Rust (2025 Edition) | by Mark Tolmacs | Medium. It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.

Today I'm going to talk about building apps you can deploy anywhere with no installation by using Rust and WebAssembly.

Getting started with Rust and WebAssembly – Grafbase

JavaScript can interface with WebAssembly to leverage its power, but this should be done with care as switching from JavaScript to WebAssembly has overhead (upfront load times and possible serialization / deserialization across the boundary), which can nullify the advantage of using WebAssembly if the switch is made too often. * For Node.js using `wasm-pack`. We’ve prepared a repository that allows you to easily get started with compiling Rust to Wasm, currently focusing on the following targets (JavaScript / TypeScript):. 1. `cargo-make` (Node.js, Deno). Here we use `cargo-make` to invoke `wasm-bindgen-cli` (which is partially what `wasm-pack` does, but it does not support Deno for example), `deno`, `node` and others. `wasm-pack` is a tool seeking to simplify workflows involving compiling Rust to WebAssembly for use in the Browser or Node.js. For Node.js this is the simplest flow, but `wasm-pack` does not currently support Deno as a target. Webpack’s Rust compilation is mostly equivalent to option 2, with a different target flag (`bundler`) for `wasm-pack` and added bundling / Webpack functionality for JS.
