/* rust_rustdoc.h — Ingest `cargo +nightly rustdoc --output-format json`
 * output into the Rust LSP type registry.
 *
 * Per the FOLLOWUP-extension Option A: when a project opts in by
 * running rustdoc once, we can ingest the resulting JSON and register
 * every item (struct, trait, fn, method) with accurate signatures.
 * That eliminates the "unseeded external crate" gap because rustdoc
 * already did the macro expansion and type resolution.
 *
 * The schema is rustdoc's "Crate" type. We handle:
 *   - paths   { id → { path: [..], kind: "struct"|"trait"|... } }
 *   - index   { id → Item { name, inner: { Function|Struct|... }, … } }
 *
 * We ignore everything we don't understand. The JSON format is unstable
 * across rustdoc versions; we tolerate missing fields gracefully and
 * just skip items we can't make sense of.
 *
 * Schema reference: https://github.com/rust-lang/rust/blob/master/src/rustdoc-json-types/lib.rs
