Crate rustdoc_processor 

Compute, cache, index, and query rustdoc JSON documentation for crates in a project’s dependency graph.

The pipeline:

1. Compute (compute::compute_crate_docs): invoke cargo rustdoc to generate JSON docs.
2. Cache (cache::RustdocGlobalFsCache): persist raw docs and secondary indexes in a SQLite database at {cache_dir}/{fingerprint}.db.
3. Index (indexing): build secondary indexes — import paths, item lookups, and external re-export tracking.
4. Query (queries::Crate, CrateCollection): look up items by path, resolve cross-crate references, and retrieve canonical import paths.

Modules
