如何防止`rust doc`向文档中添加依赖项？

我刚刚开始玩Rust,并试图为我编写的代码生成文档.当我发布时cargo doc,我看到了一些有点奇怪的东西.

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)

当我打开时my_project/target/doc/my_project/index.html,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,因此我的文档仅显示如何使用我的代码.

我怎样才能做到这一点？

[root]
name = "my_project"
version = "0.0.1"
dependencies = [
 "regex 0.1.41 (registry+https://github.com/rust-lang/crates.io-index)",
]

[[package]]
name = "aho-corasick"
version = "0.3.4"
source = "registry+https://github.com/rust-lang/crates.io-index"
dependencies = [
 "memchr 0.1.7 (registry+https://github.com/rust-lang/crates.io-index)",
]

[[package]]
name = "libc"
version = "0.2.2"
source = "registry+https://github.com/rust-lang/crates.io-index"

[[package]]
name = "memchr"
version = "0.1.7"
source = "registry+https://github.com/rust-lang/crates.io-index"
dependencies = [
 "libc 0.2.2 (registry+https://github.com/rust-lang/crates.io-index)",
]

[[package]]
name = "regex"
version = "0.1.41"
source = "registry+https://github.com/rust-lang/crates.io-index"
dependencies = [
 "aho-corasick 0.3.4 (registry+https://github.com/rust-lang/crates.io-index)",
 "memchr 0.1.7 (registry+https://github.com/rust-lang/crates.io-index)",
 "regex-syntax 0.2.2 (registry+https://github.com/rust-lang/crates.io-index)",
]

[[package]]
name = "regex-syntax"
version = "0.2.2"
source = "registry+https://github.com/rust-lang/crates.io-index"

erip.. 24

我找到了答案:cargo doc --no-deps.
