Skip to main content Crate guard_core_engine Copy item path Source behavior The behavior-rule engine, ported from the reference behavior handler
and its mixins. The go port is the structural template. binary_islands Binary islands reduction, ported from guard_core/detection_engine/ binary_islands.py (upstream commit 5f399234). body_scan Request body value extraction: the engine-side port of the reference
body-scanning split, mirroring the Go engine’s bodyscan.go. cloud_fetch The cloud-provider range lifecycle: the fetch payload parsers, the
Azure ServiceTags URL extraction, the refresh cadence with the
single-flight gate, and the store-backed cache layers. cloud_provider The cloud-provider IP table and block selectors. compiler cors CORS handling, ported from the reference response-side CORS surface. custom_checks The custom function seams: the reference pipeline’s ninth and
seventeenth checks. decorators The reference decorator system (guard_core/decorators/*.py): the
SecurityDecorator detect Public detection entry point: the spec 4.0.2 SusPatternsManager.detect
pipeline (preprocess, four scan views, semantic analysis, scoring). detection_exclusions Per-request detection exclusion resolution and the multi-surface request
scan. distributed The distributed-store seam: the engine-side traits and key helpers
for Redis-backed (or any backend) rate limiting and bans. dynamic_rules The dynamic-rules carrier: the reference DynamicRules wire model
and its manager-side logic (handlers/_dynamic_rule_*.py +
_dynamic_rules.py). emergency_mode The emergency-mode gate: the reference pipeline’s second check. geo The country gate: whitelist_countries and blocked_countries. headers_auth The required-headers and authentication gate. https_enforcement The HTTPS enforcement gate: the reference pipeline’s third check. ip_ban The dynamic IP ban store and the auto-ban engine: ban_ip with a
duration, expiry-honoring is_banned, and the per-IP violation counters
with the threshold resolution both are fed by. ip_extraction The client-IP extraction from the forwarded chain: the reference
_utils/ip_extraction.py’s depth-limited X-Forwarded-For walk, driven
by the trusted_proxies / trusted_proxy_depth knobs. ip_gate The global IP gate: whitelist, blacklist, and exempt_ips. json_walk Ordered JSON body walk, ported from the Go engine’s jsonwalk.go, which
ports guard_core/_utils/body_json_scan.py and embedded_json_scan.py. multipart_scan Line-based multipart scanner mirroring the extracted-value semantics of
Python’s email feedparser for multipart/form-data bodies. path_matching The exclude_paths matcher: the reference
core/validation/path_matching.py. patterns Detection wiring for the compiled pattern table and its dispatch. payload The data contracts the reference passes between the configuration
surface, the block hook, and the response-side pass. performance_monitor The pattern performance monitor: per-pattern execution stats, the
anomaly-detection trio, and the sanitized callbacks. preprocessor Content preprocessing ported from guard_core/detection_engine/preprocessor.py. rate_limit The sliding-window rate limiter: per client IP, global scope or per
endpoint. redis_schema The Redis key schema (spec section 08, interop): every key pattern,
every value format, and the ban-key migration, byte-compatible with the
Go and Python family ports. redos The pattern-safety chain: the full port of the reference’s ReDoS
defenses (guard_core/detection_engine/_redos_*). referrer The route referrer gate: the reference pipeline’s eighth check. request_limits The request size and content-type gate: max_request_size and
allowed_content_types. request_logging The request-logging pass: the reference pipeline’s fourth check. route_config The per-route configuration carrier: the reference RouteConfig
(guard_core/decorators/route_config.py). scan_budget Per-request regex scan time budget: the reference
detection_max_scan_seconds (guard_core/_utils/detection_scan.py,
_scan_time_budget_exhausted). security_config The unified configuration surface: the reference SecurityConfig
(guard_core/_security_config_fields.py, 129 fields) fieldized for the
Rust family. security_headers Security headers management, ported from the reference handler. semantic time_window The route time-window gate: the reference pipeline’s tenth check. user_agent The blocked user-agent pattern filter.
