可执行文件实际上需要目标目录中的哪些文件?

Which files from the target directory are actually required by the executable?

我的程序编译后'zagir',release文件夹有200MiB多的大小,这对于我写的程序来说是可笑的。因此,我尝试检查是否只有 'zagir' 可执行文件在隔离运行并且确实如此。

但令人困惑的是,release 文件夹还包括 libzagir.rlib 文件以及 .d 文件和一堆其他文件夹。

  1. 它们到底是什么?
  2. 他们真的需要吗?
  3. 当这些文件被忽略时,我会在执行过程中出错吗?
  4. 我应该为完整的可执行文件捆绑哪些文件?

Which files from the target directory are actually required by the executable

None 个,除了可执行文件本身。默认情况下,Rust 生成 静态链接的二进制文件

其他文件只是由 Cargo 维护的构建工件,以便更有效地重建代码。它们包括诸如您的依赖项之类的东西。

您可能会找到的一些文件的非详尽示例:

  • *.d — Makefile 兼容依赖列表
  • *.rlib — Rust 库文件。包含依赖的编译代码
  • build — 用作临时文件的构建脚本目录 space
  • deps — 你编译的依赖项
  • examples — 来自 examples 目录的二进制文件
  • incremental — 增量编译缓存目录
  • *-{hash} — 来自 cargo test
  • 的二进制文件
  • 可执行文件——你的目标二进制文件

其中一些已记录在案 in the Cargo source code
