🦀️Rust 移动端开发体验

使用 Rust 写了一个移动端的跨平台日志库：s1rius/ezlog: A cross-platform file logging library (github.com)

大型公司在移动端使用 Rust

Google 在 2021 年将 Rust 引入 Android Rust in the Android platform
Mozilla 使用 Rust 编写跨平台应用服务组件Firefox Application Services
飞书客户端非 UI 部分使用 Rust 跨平台实现

个人开发者在移动端的尝试 Rust 的案例

更多的案例收录，可以参看这篇Rust 移动开发与跨平台模式探究。从以上的例子来看，大概率是可行的，还要对具体的需求进行验证。

项目简述

主要功能

使用 mmap 做文件映射
认证加密
zlib 压缩
日志回捞
日志清理
命令行解析工具

可行性验证

先查找主要功能是否有对应的 Rust 开源实现。

开源社区早已实现好了：）复制开源库中的示例，借助android-ndk-rs。在 android 真机运行，查看日志输出，符合预期。项目中使用android ndk rs的例子，可以查看examples/android_preview

开发中碰到的问题及解决

iOS

iOS 端的开发流程为

Rust 编码
通过 cbindgen 生成头文件
编译多平台静态库
把静态库和头文件打包成 XCFramework，并依赖
实现 Swift 绑定
测试，发布

在对比了多种依赖静态库的方式之后，发现XCFramework对多平台的支持，更适合这个项目。更多 XCFramework 的相关资料可以看这几篇文章distributing universal ios frameworks as xcframeworks using cocoapods, Static libraries into XCFramework,From Rust To Swift。在项目中的构建使用，可以参看ios/b_ios.sh脚本。

Swift 与 C 的互相调用，很多概念需要了解。在被Unmanaged, @escaping,@convention,UnsafePointer,UnsafeBufferPointer, UnsafeMutableRawPointer 折磨许久之后，终于可以在 Swift 中拿到 Rust 的回调了。

Cocoapods 支持 XCFramework，尝试了 SPM，找不到符号的问题没有解决。暂时放一放。在花费了以天计的时间成本之后，终于在 Cocoapods 成功发布。

对比一下三个包管理工具的从注册到发布的时间成本，从简单到繁琐的排序是 Cargo < Cocoapods < Maven。

随着苹果在 XCode14 中废弃了 bitcode，Rust 在 iOS/MacOS 中最大的痛点也就消失了。

android FFI

android 上 Rust 与 JNI 的互调和 C/C++的区别不大。同样要考虑变量的生命周期，全局的 JavaVM 引用，类加载到 JVM，native 线程在 JVM 的 attach 和 detach，详细的示例代码可以查看jni-rs。

得益于 Rust 的生命周期管理，一些内存清理操作 Rust 已经处理了，不需要我们再手动的处理。

rust

impl<'a: 'b, 'b> Drop for JavaStr<'a, 'b> {
    fn drop(&mut self) {
        match self.env.release_string_utf_chars(self.obj, self.internal) {
            Ok(()) => {}
            Err(e) => warn!("error dropping java str: {}", e),
        }
    }
}

android 动态库大小

因为用户对 RAM，流量的关心和 Android 版本向前兼容原因，android 开发中对包体积大小是敏感的。对于 Rust 编译产物体积较大的问题，在查阅了Minimizing Rust Binary Size文章后，在 release 模式开启优化。

我们将 XLog，Logan 都加入到 Demo 的依赖中，对比 release apk 中的 64 位动态库大小，如图所示

	EZLog(0.1.2)	EZLog(with backtrace)	XLog(1.2.5)	XLog(with libc++)	Logan(1.2.4)
so 大小	370.6KB	451.6KB	277.1KB	537KB	27.5KB

Rust 编译的动态库大小是最大的，不过也没有太过于夸张，随着手机硬件的进一步提升，应该不会是制约 Rust 在 android 中应用的原因。

崩溃？

不同的情况下，需要不同的方式

在开发，测试阶段，由于编写错误或者代码混淆等问题，导致类，方法无法找到的情况，我们希望程序能直接崩溃，尽早的暴露问题。
产品上线后，因为适配问题或者用户操作导致 bug 出现，导致某个模块的不可用。我们希望错误只限定在这个模块，不影响其他的功能，并上报这个错误

Rust 的错误分为可恢复和不可恢复的错误。Rust 初始化线程的 panic 会导致进程的退出。一些解决方法:

只在需要崩溃时使用 panic 宏
在 Clippy 中加入使用 unwrap 和 except 的警告
替换 [start..end] 为 get(start..end)
FFI 中 catch_unwind

即使自己的代码中没有 panic 调用，依赖库中也可能会调用。所以需要提供在生产环境中崩溃排查的能力。

崩溃排查

初始化时设置 panic hook。

rust

#[cfg(not(feature = "backtrace"))]
fn hook_panic() {
    std::panic::set_hook(Box::new(|p| {
        event!(panic & format!("ezlog: \n {p:?}"));
    }));
}

在崩溃时会回调拿到 PanicInfo

yaml

PanicInfo { payload: Any { .. }, message: Some(asdf), location: Location { file: "ezlog-core/src/lib.rs", line: 119, col: 5 },

PanicInfo 中有错误信息，panic 的文件路径和代码位置。这样能粗略的排查 bug。如果想拿到具体的堆栈信息，我们还需要依赖 backtrace，这样最后动态库的大小会增加 80KB 左右

rust

#[cfg(feature = "backtrace")]
fn hook_panic() {
    std::panic::set_hook(Box::new(|p| {
        let bt = Backtrace::new();
        event!(panic & format!("ezlog: \n {p:?} \n{bt:?} \n"));
    }));
}

添加 backtrace 依赖后，iOS 的崩溃堆栈打印如下
