A command like in-memory database in rust

• ⚡ Command-like TCP Protocol: Utilizes a custom, command-oriented protocol over TCP for structured communication between clients and the in-memory database server.
• 💨 Efficient In-Memory Storage: Crafted in Rust, "iris" is your go-to for a fast and reliable in-memory database.
• 👤 User-Friendly Commands: Easily communicate with the database server using simple commands like SET, GET, DELETE, and more. It's designed to offer an intuitive experience for developers of any skill level.

Communication in "iris" follows a structured message format, allowing clients to send commands to the server for processing. The message format consists of the following components:

1. Command Type: A three-byte identifier specifying the type of command being sent.
2. ID: Variable-length identifier for the command, used for tracking and processing purposes.
3. Data: Variable-length payload containing additional information required for the command.

SET foo bar
│   │   └─ Data
│   └───── ID
└───────── COMMAND

Upon receiving a command, the server parses the message according to the defined format and processes the request accordingly. The server responds with a message in the following format:

1. Status: A two or three-byte identifier indicating the status of the command execution. It can be either "OK" for successful execution or "ERR" for error conditions.
2. Response: A variable-length payload containing additional information or the result of the command execution. This could include data retrieved from the database or an error message.

ok foo
│  └─ Response
└──── Status
