This project involves creating a Rock-Paper-Scissors (RPS) game server in Rust using async-await syntax and async-std. Learned handling asynchronous operations, managing tasks concurrently, and implementing a game logic system.

Async Function: play_command

The play_command function manages the flow of a game round, handling player interactions, weapon selection, and outcome determination. It utilizes asynchronous features to coordinate between players and ensures a smooth gameplay experience.

Key Aspects:

• Asynchronous communication with peers using async-await syntax.
• Utilization of channels (channel::Sender) for inter-task communication.
• Handling timeouts (play_timeout and weapon_timeout) for responsive gameplay.

Async Function: weapon_loop

The weapon_loop function allows a player to choose their weapon within a specified timeout. It captures user input, validates it, and returns the selected weapon or None if the timeout occurs.

Key Aspects:

• Asynchronous user input handling for weapon selection.
• Timeout management to ensure responsive user interactions.
• Utilization of a loop for continuous user prompts until a valid input or timeout.

Async Function: play_matchmaker_task

The play_matchmaker_task function acts as a matchmaker, pairing players for RPS matches. It listens for play requests, manages timeouts, and initiates referee tasks for matched players.

Key Aspects:

• Utilization of asynchronous channels (channel::Receiver) for receiving play requests.
• Timeout handling for matchmaking to prevent indefinite waiting.
• Dynamic task creation (task::Builder) for referee tasks.

Async Function: referee_task

The referee_task function orchestrates a single RPS match between two players. It coordinates the exchange of weapons, determines the outcome, updates game statistics, and communicates results to players.

Key Aspects:

• Use of oneshot::Sender for bidirectional communication between referee and players.
• Graceful handling of player disconnections during different phases of the match.
• Statistical updates to a shared database (DataBase) for game outcomes.
