debug_rust_network.sh

#!/bin/bash

# This script is designed to help debug networking issues between the Urukhai Rust server and client.
# It performs the following steps sequentially:
# 1. Navigates to the rust-urukhai directory where the Cargo projects are located.
# 2. Sources the cargo environment script to ensure cargo is in the PATH.
# 3. Compiles the server and client applications using 'cargo build'.
# 4. Creates temporary log files for both the server and client to capture their output.
# 5. Starts the server in the background and logs its process ID (PID).
# 6. Pauses for a second to allow the server to initialize properly.
# 7. Runs the client, which will attempt to connect to the server.
# 8. After the client finishes, it terminates the server process using the stored PID.
# 9. Displays the captured logs from both the server and client for debugging.
# 10. Cleans up the temporary log files.
