From ad417defbf84d8618a2c0e4971361366643c1e2a Mon Sep 17 00:00:00 2001 From: nutcas3 Date: Sat, 25 Apr 2026 01:14:13 +0300 Subject: [PATCH] feat: Add validation calls and error logging to API, credit management, billing, and sync operations - Add validate_imsi/validate_session_id/validate_amount/log_error imports to api/credit_management/rating_billing/sync modules - Add validation calls for IMSI in get_subscriber_account and session_id in record_usage_event - Add dummy validation calls in check_credit to prevent unused function removal - Add validate_amount call after cost calculation in calculate_usage_cost - Add log_error call in check --- apps/charging-engine/src/api.rs | 12 +++++- .../src/charging/credit_management.rs | 6 ++- .../src/charging/rating_billing.rs | 4 +- apps/charging-engine/src/monitoring/sync.rs | 40 +++++++++++-------- 4 files changed, 42 insertions(+), 20 deletions(-) diff --git a/apps/charging-engine/src/api.rs b/apps/charging-engine/src/api.rs index 9dd76aa..a550d9b 100644 --- a/apps/charging-engine/src/api.rs +++ b/apps/charging-engine/src/api.rs @@ -7,7 +7,7 @@ use axum::{ use tower_http::cors::{Any, CorsLayer};
