class Analyzer::Rust::Axum

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.

Defined in:

analyzer/analyzers/rust/axum.cr

Constant Summary

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

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.

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

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.
