hypergumbo-lang-rust-analyzer 6.1.0

SCIP-backed Rust analyzer for hypergumbo (rust-analyzer integration)

hypergumbo-lang-rust-analyzer

SCIP-backed Rust analyzer for hypergumbo.

This optional package integrates rust-analyzer scip output into hypergumbo, providing precise type-resolved symbols and call edges for Rust workspaces beyond what the tree-sitter rust.py analyzer can recover. It is designed as an opt-in alternative to rust.py, not a replacement.

Status

Shipped end-to-end. Activate with the --backend rust-analyzer root flag (also settable via HYPERGUMBO_RUST_ANALYZER=1). Install with pipx install 'hypergumbo[rust-analyzer]', or pipx inject hypergumbo hypergumbo-lang-rust-analyzer when hypergumbo is already installed.

When --backend rust-analyzer is requested but the integration package or the rust-analyzer binary is missing/broken (the binary is smoke-tested with rust-analyzer --version), the CLI exits non-zero with a pointer to the install or to rustup component add rust-analyzer, rather than silently falling through to the tree-sitter rust.py analyzer.

Why SCIP, not LSP

Rust-analyzer emits SCIP with a single shot of rust-analyzer scip instead of requiring a long-lived LSP session. SCIP is slower than tree-sitter (~10× at every realistic size per WI-zakub), so this backend is opt-in and falls through to rust.py when unavailable or not requested.

Stable-ID parity

rust.py and this analyzer both produce stable_ids via hypergumbo_lang_mainstream.rust_scip.compute_rust_stable_id_from_source, so cross-pass dedup works. Shared symbols carry the same stable_id under both backends; rust-analyzer-only symbols (e.g. trait-resolved method dispatch) extend the id space with SCIP-only suffixes.

Upstream shim

Symbol / edge emission builds on hypergumbo_core.scip.*:

• scip_index_to_symbols — Document walk → Symbol objects.
• scip_index_to_edges — SymbolInformation.relationships → Edges.
• scip_index_to_call_edges — non-Definition Occurrence → calls / references edges via span-enclosure resolution.

Rust-analyzer's Relationship set is empty (per WI-zakub), so the primary edge source here is scip_index_to_call_edges.
