Crates

The item-level reference for every Rust crate in the workspace is its rustdoc. The workspace is publish = false, so docs.rs never builds it, and rustdoc renders a whole site of its own that is far too large to commit. It is therefore the one reference surface that lives outside this site’s chrome, as Developer Documentation records.

Where to get it

• Locally: cargo doc --workspace --no-deps --open builds it and opens it in a browser. Add --document-private-items to see what the gate sees.
• From CI: the Rust gate builds it on every run (mise run doc-check-rust, which denies broken and ambiguous intra-doc links over every item, private ones included). On each push to master, the Rust job uploads that build as the rustdoc workflow artifact; download it from the run and open a crate’s index.html, such as capsule_sdk/index.html.

It is not hosted beside this site yet: publishing is still a manual bun run deploy, and hosting rustdoc waits on deploy automation.

Which crate to start from

Which crate owns which module, and which design doc owns each module’s contract, is the Module Map. For a client, start from capsule-sdk, whose overview is the Rust SDK page.
