Rust Doc

rust_doc

Generates code documentation.

Example: Suppose you have the following directory structure for a Rust library crate:

[workspace]/
    WORKSPACE
    hello_lib/
        BUILD
        src/
            lib.rs

To build rustdoc documentation for the hello_lib crate, define a rust_doc rule that depends on the the hello_lib rust_library target:

package(default_visibility = ["//visibility:public"])

load("@rules_rust//rust:defs.bzl", "rust_library", "rust_doc")

rust_library(
    name = "hello_lib",
    srcs = ["src/lib.rs"],
)

rust_doc(
    name = "hello_lib_doc",
    crate = ":hello_lib",
)

Running bazel build //hello_lib:hello_lib_doc will build a zip file containing the documentation for the hello_lib library crate generated by rustdoc.

ATTRIBUTES

nameA unique name for this target.Namerequired
crateThe label of the target to generate code documentation for.

rust_doc can generate HTML code documentation for the source files of rust_library or rust_binary targets.

rustc_flagsDeprecated: use rustdoc_flags insteadList of stringsoptional[]
rustdoc_flagsList of flags passed to rustdoc.

These strings are subject to Make variable expansion for predefined source/output path variables like $location, $execpath, and $rootpath. This expansion is useful if you wish to pass a generated file of arguments to rustc: @$(location //package:target).

rust_doc_test

Runs Rust documentation tests.

Example:

Suppose you have the following directory structure for a Rust library crate:

[workspace]/
WORKSPACE
hello_lib/
    BUILD
    src/
        lib.rs

To run documentation tests for the hello_lib crate, define a rust_doc_test target that depends on the hello_lib rust_library target:

package(default_visibility = ["//visibility:public"])

load("@rules_rust//rust:defs.bzl", "rust_library", "rust_doc_test")

rust_library(
    name = "hello_lib",
    srcs = ["src/lib.rs"],
)

rust_doc_test(
    name = "hello_lib_doc_test",
    crate = ":hello_lib",
)

Running bazel test //hello_lib:hello_lib_doc_test will run all documentation tests for the hello_lib library crate.

These can be either other rust_library targets or cc_library targets if linking a native library.
