应用大小

虽然 Tauri 默认提供非常小的二进制文件，但稍微突破一下限制也无妨，因此这里有一些技巧和窍门可以帮助你达到最佳效果。

¥While Tauri by default provides very small binaries it doesn’t hurt to push the limits a bit, so here are some tips and tricks for reaching optimal results.

Cargo 配置

¥Cargo Configuration

你可以对项目进行的最简单的前端无关大小改进之一是向其添加 Cargo 配置文件。

¥One of the simplest frontend agnostic size improvements you can do to your project is adding a Cargo profile to it.

根据你使用的是稳定版还是夜间版 Rust 工具链，可用的选项会略有不同。除非你是高级用户，否则建议你坚持使用稳定的工具链。

¥Dependent on whether you use the stable or nightly Rust toolchain the options available to you differ a bit. It’s recommended you stick to the stable toolchain unless you’re an advanced user.

Stable

src-tauri/Cargo.toml

[profile.dev]
incremental = true # Compile your binary in smaller steps.

[profile.release]
codegen-units = 1 # Allows LLVM to perform better optimization.
lto = true # Enables link-time-optimizations.
opt-level = "s" # Prioritizes small binary size. Use `3` if you prefer speed.
panic = "abort" # Higher performance by disabling panic handlers.
strip = true # Ensures debug symbols are removed.

Nightly

src-tauri/Cargo.toml

[profile.dev]
incremental = true # Compile your binary in smaller steps.
rustflags = ["-Zthreads=8"] # Better compile performance.

[profile.release]
codegen-units = 1 # Allows LLVM to perform better optimization.
lto = true # Enables link-time-optimizations.
opt-level = "s" # Prioritizes small binary size. Use `3` if you prefer speed.
panic = "abort" # Higher performance by disabling panic handlers.
strip = true # Ensures debug symbols are removed.
trim-paths = "all" # Removes potentially privileged information from your binaries.
rustflags = ["-Cdebuginfo=0", "-Zthreads=8"] # Better compile performance.

这不是对所有可用选项的完整引用，仅仅是我们想特别引起注意的选项。

¥This is not a complete reference over all available options, merely the ones that we’d like to draw extra attention to.

:::

• 增量： 以较小的步骤编译二进制文件。

  ¥incremental: Compile your binary in smaller steps.

• codegen-units: 以编译时优化为代价加快编译时间。

  ¥codegen-units: Speeds up compile times at the cost of compile time optimizations.

• lto： 启用链接时间优化。

  ¥lto: Enables link time optimizations.

• opt-level: 确定编译器的焦点。使用 3 优化性能，使用 z 优化大小，使用 s 进行中间优化。

  ¥opt-level: Determines the focus of the compiler. Use 3 to optimize performance, z to optimize for size, and s for something in-between.

• 恐慌： 通过消除恐慌展开来减小大小。

  ¥panic: Reduce size by removing panic unwinding.

• strip: 从二进制文件中剥离符号或调试信息。

  ¥strip: Strip either symbols or debuginfo from a binary.

• rpath： 通过将信息硬编码到二进制文件中，帮助查找二进制文件所需的动态库。

  ¥rpath: Assists in finding the dynamic libraries the binary requires by hard coding information into the binary.

• trim-paths: 从二进制文件中删除潜在的特权信息。

  ¥trim-paths: Removes potentially privileged information from binaries.

• rustflags： 根据配置文件设置 Rust 编译器标志。

  ¥rustflags: Sets Rust compiler flags on a profile by profile basis.

  • -Cdebuginfo=0：是否应在构建中包含调试信息符号。

    ¥-Cdebuginfo=0: Whether debuginfo symbols should be included in the build.

  • -Zthreads=8：增加编译期间使用的线程数。

    ¥-Zthreads=8: Increases the number of threads used during compilation.
