添加了 rust 文件的 Chromium Android arm 构建上的 clang++ 错误

问：

在尝试基于结帐 100.0.4896.127 为 Android 臂拱构建 Chromium 时，我遇到了一些奇怪的行为。我添加了一些 rust 代码，对于 arm64 arch，它构建得很好，但是如果我尝试为 arm arch 编译相同的代码，我会收到以下错误：

这是我 args.gn：

target_os = "android"
is_debug = false
target_cpu = "arm"
is_component_build = false
is_official_build = true
android_channel = "stable"
proprietary_codecs = true
ffmpeg_branding = "Chrome"
enable_widevine = true
enable_nacl = false
use_official_google_api_keys=false
google_api_key = "no"
google_default_client_id = "no"
google_default_client_secret = "no"
enable_full_stack_frames_for_profiling = false
treat_warnings_as_errors=false

我之前一直在使用 96.0.4664.104 Chromium 结帐的相同代码，没有任何问题，但现在我花了很多时间试图解决这个问题，但不幸的是没有成功。

我将不胜感激任何提示！
