Overview

Axum analyzer (tree-sitter port). Each .rs file is parsed once with the vendored Rust grammar; route registrations are picked up by walking call_expression nodes whose function is a field_expression named route. Handler bodies are matched against a same-file function_item index so callee extraction shares the parsed tree instead of re-scanning the file with regexes and a body-text wrapper.

Constant Summary

BUILDER_ROUTE_EMIT_NAMES = Set {"get", "post", "put", "delete", "patch", "head", "options", "any", "query", "unauthenticated_get", "unauthenticated_post", "unauthenticated_put", "unauthenticated_delete", "unauthenticated_patch", "unauthenticated_head", "unauthenticated_options", "unauthenticated_any", "unauthenticated_query"}

CROSS_NEST_EVIDENCE_RE = Regex.union(".nest(", ".nest_api_service(", ".merge(")

Precompiled union for build_cross_nest_index's per-file evidence gate, so it costs a single PCRE2 match instead of three naive substring scans.

EXTRACTOR_PARAM_RES = {"Query" => {/Query\s*\(\s*[^)]+\s*\)/, /:\s*(?:[A-Za-z_]\w*::)*Query\b/}, "Json" => {/Json\s*\(\s*[^)]+\s*\)/, /:\s*(?:[A-Za-z_]\w*::)*Json\b/}, "Form" => {/Form\s*\(\s*[^)]+\s*\)/, /:\s*(?:[A-Za-z_]\w*::)*Form\b/}}

Precompiled per extractor type; interpolated regex literals here would be recompiled on every function parameter.

HTTP_VERBS = Set {"get", "post", "put", "delete", "patch", "head", "options", "any", "query"}

Verbs accepted as the inner handler call (get(...), post(...), …). Anything outside this set is treated as GET to match the legacy fallback the regex analyzer used. any covers axum::routing::any(handler) — a verb-agnostic registration commonly used for WebSocket upgrades and reverse-proxy fallbacks.

NEST_NAMES = Set {"nest", "nest_api_service"}

.nest("/p", router) and aide's .nest_api_service("/p", router) both mount a sub-router under a path prefix.

ROUTER_EMIT_NAMES = Set {"route", "route_service", "nest_service", "fallback", "fallback_service", "api_route", "api_route_with"}

Field-call names whose extracted shape extract_route knows how to read. route_service, nest_service, and the two fallback* variants surface in roughly half of all real-world axum apps (static-file mounts, SPA fallbacks, websocket upgrades).

SERVICE_METHOD = "ANY"

Method emitted for service-shaped registrations (route_service, nest_service, fallback_service). Services aren't bound to a specific HTTP method — tower-http::services::ServeDir accepts whatever the client sends — so we mirror axum's any verb.

UTOIPA_INDEX_EVIDENCE_RE = Regex.union("OpenApiRouter", ".routes(")

Precompiled union for build_utoipa_prefix_index's per-file evidence gate, so it costs a single PCRE2 match instead of two naive substring scans.

UTOIPA_VERBS = Set {"get", "post", "put", "delete", "patch", "head", "options", "trace"}
