16Generates code documentation.
17
18Example:
19Suppose you have the following directory structure for a Rust library crate:
20
21```
22[workspace]/
23    WORKSPACE
24    hello_lib/
25        BUILD
26        src/
27            lib.rs
28```
29
30To build [`rustdoc`][rustdoc] documentation for the `hello_lib` crate, define     a `rust_doc` rule that depends on the the `hello_lib` `rust_library` target:
31
32[rustdoc]: https://doc.rust-lang.org/book/documentation.html
33
34```python
35package(default_visibility = ["//visibility:public"])
36
37load("@rules_rust//rust:defs.bzl", "rust_library", "rust_doc")
38
39rust_library(
40    name = "hello_lib",
41    srcs = ["src/lib.rs"],
42)
43
44rust_doc(
45    name = "hello_lib_doc",
46    crate = ":hello_lib",
47)
48```
49
50Running `bazel build //hello_lib:hello_lib_doc` will build a zip file containing     the documentation for the `hello_lib` library crate generated by `rustdoc`.

75Runs Rust documentation tests.

89
90To run [documentation tests][doc-test] for the `hello_lib` crate, define a `rust_doc_test`         target that depends on the `hello_lib` `rust_library` target:
91
92[doc-test]: https://doc.rust-lang.org/book/documentation.html#documentation-as-tests
93
94```python
95package(default_visibility = ["//visibility:public"])

106    crate = ":hello_lib",
107)
108```
109
110Running `bazel test //hello_lib:hello_lib_doc_test` will run all documentation tests for the `hello_lib` library crate.
