# CLEAN — actix-web
|
|
|
|
Scanned 2026-03-29 for CWE-407 (algorithmic complexity).
|
|
|
|
## Findings
|
|
|
|
- `actix-web/src/middleware/logger.rs` — `exclude` is `HashSet<String>`: O(1) per-request lookup. CLEAN.
|
|
- `actix-web/src/http/header/accept_encoding.rs` — `supported_set` collected as `HashSet<&Encoding>` before iteration. CLEAN.
|
|
- `actix-web/src/introspection.rs` — `update_unique` uses `Vec::contains()` for HTTP methods/guards/patterns, but these lists are bounded to <10 items each and only called once at app startup (route registration), not per request. Not actionable.
|
|
- All other `contains()` calls use bitflags, ranges, or string substring checks — not collection membership.
|
|
|
|
**Result: No actionable CWE-407 defects.**
