Rust documentation helper that helps a Rust crate developer generate a file llms.txt that helps provide context to large language models (LLMs).

Thanks to excellent work by the Rust team, rustdoc team, and rustdoc-md team.

Install:

cargo install rustdoc-llms

Use the tool when you're working on a crate and you want to document it:

The tool creates two files:

• target/doc/foo_bar.json (this uses your own crate naming convention)

• target/doc/llms.txt (this is a markdown file created by rustdoc-md)

If you like, you can copy these files to the top level of your repository, which can make the files easier to find for search engines and AI systems:

cp target/doc/foo_bar.json llms.json
cp target/doc/llms.txt llms.txt

This Rust crate is deliberately small and simple. The purpose is to make it slightly-easier to generate llms based on what's currently easy and available for Rust crate developers.

Currently this tool calls existing command line interfaces, using cargo and rustdoc-md with specialized compiler flags. If this tool is useful in practice, then I intend to iterate to add command line arguments, options, tests, and the like.

Pull requests are welcome. Issues are welcome.

This implements the help description here.

Step 1: Generate JSON documentation:

RUSTC_BOOTSTRAP=1 RUSTDOCFLAGS="-Z unstable-options --output-format json" cargo doc --no-deps

Step 2: Convert from JSON into Markdown:

rustdoc-md --path target/doc/foo_bar.json --output target/doc/foo_bar.md

Step 3: Copy from Markdown file into LLMs file:

cp target/doc/foo_bar.json llms.json
cp target/doc/foo_bar.md llms.txt
