Dogfood!

Have a test that uses libsyntax (or syn or whatever) to parse the source files of rust-docstrings and validate they are Nicely Documented™.

Start by inspecting the Rust source files in rust-docstrings and the available libsyntax or syn parsing options. Define a test that parses the project sources and verifies their documentation; done means the test runs reliably and fails when source items are not documented.
