我刚刚开始玩Rust，并试图为我编写的代码生成文档.当我发行cargo doc美元时，我看到了一些奇怪的东西.

21:53 $ cargo doc
   Compiling regex-syntax v0.2.2
   Compiling libc v0.2.2
   Compiling memchr v0.1.7
   Compiling aho-corasick v0.3.4
   Compiling regex v0.1.41
   Compiling my_project v0.0.1 (path/to/my_project)

当我打开my_project/target/doc/my_project/index.html时，我注意到所有依赖项都包含在我的文档中:

我希望这些依赖项的文档对用户隐藏，这样我的文档只显示如何使用my个代码.

我该怎么做？

Cargo.lock
