From 250dfa29da52807d65f06cf7a0bdf1543b9ae246 Mon Sep 17 00:00:00 2001 From: Robin B Date: Tue, 9 Dec 2025 22:19:08 +0100 Subject: [PATCH 1/2] feat: replace .expect() and .unwrap() with proper error handling - Fix Server-Timing header parsing with graceful fallback - Fix IP address parsing with meaningful error messages - Fix client initialization with proper error handling - Fix HTTP request handling with graceful degradation - Add comprehensive tests for error handling scenarios - Add Server-Timing header parsing tests - Add Default implementation for SpeedTestCLIOptions The application now handles errors gracefully instead of panicking, providing better user experience and more robust operation.
