You might want to build documentation of the various components available like the standard library. There’s two ways to go about this. You can run rustdoc directly on the file to make sure the HTML is correct, which is fast. Alternatively, you can build the documentation as part of the build process through x.py. Both are viable methods since documentation is more about the content.
./x.py doc --stage 1
First the compiler and rustdoc get built to make sure everything is okay and then it documents the files.
./x.py doc src/doc/book ./x.py doc src/doc/nomicon ./x.py doc src/doc/book src/libstd
Much like individual tests or building certain components you can build only the documentation you want.
Compiler documentation is not built by default. There's a flag in config.toml for achieving the same. But, when enabled, compiler documentation does include internal items.
Next open up config.toml and make sure these two lines are set to true:
docs = true compiler-docs = true
When you want to build the compiler docs as well run this command:
This will see that the docs and compiler-docs options are set to true and build the normally hidden compiler docs!
The documentation for the rust components are found at rustc doc.
