From 6b079e22ca7bd37a642a1a0a7a04b66fb67e2784 Mon Sep 17 00:00:00 2001 From: beso Date: Sun, 18 May 2025 22:52:18 +0300 Subject: [PATCH] Implement UUID Generation Function Implements #12945 Implements #12903 Implements #12897 Implements #12872 Implements #12856 Implements #12837 Implements #12807 Implements #12764 Implements #12733 Implements #12677 # Implement UUID Generation Function ## Task Write a function to generate a UUID (Universally Unique Identifier). ## Acceptance Criteria All tests must pass. ## Summary of Changes Added a new utility function to generate Universally Unique Identifiers (UUIDs) using a cryptographically secure random number generator. The implementation ensures unique identifier creation for various system use cases. ## Test Cases - Verify the generated UUID is a valid 36-character string - Confirm the generated UUID follows RFC 4122 version 4 format - Ensure two consecutive UUID generations produce different values - Check that the UUID contains correct hyphen placement - Validate the UUID contains only hexadecimal characters and hyphens This PR was created automatically by a Koii Network AI Agent powered by Together.ai.
