How it works

This app uses the tokio runtime to handle asynchronous tasks. The tokio runtime is a low-level, zero-cost abstraction over futures. It provides several tools to help you write asynchronous code, including:

• The tokio::spawn function for executing a future on a thread pool
• Asynchronous versions of common std types, including TCP streams (tokio::net::TcpStream), UDP sockets (tokio::net::UdpSocket), and channels (tokio::sync::mpsc and tokio::sync::oneshot)
• The tokio::sync::Mutex type, an asynchronous version of std::sync::Mutex
• Timer types, including tokio::time::Instant and tokio::time::Duration
• The tokio::main macro, which makes it easy to run a tokio application

This app is a simple key-value store that allows you to set, get, and delete keys. It uses the redis protocol to communicate with the redis-cli. The redis-cli is a command line interface for redis that allows you to interact with the redis server. The redis-cli is a simple program that allows you to send commands to the server and read the replies sent back.

The redis protocol is a text-based protocol that uses the client-server model. The client sends a command to the server and the server responds with a reply. The client and server communicate using a TCP connection. The client sends a command to the server and the server responds with a reply. T

Commands

Command	Description
redis-cli set key value	Set a key
redis-cli get key	Get a key
redis-cli set key value ex time	Set an expiration time for a key
redis-cli ttl key	Get the remaining time for a key
redis-cli del key	Delete a key
redis-cli flush	Delete all keys

Examples

Command	Description
redis-cli set name john	Set the key name to the value john
redis-cli get name	Get the value of the key name
redis-cli set name john ex 10	Set the key name to the value john and set an expiration time of 10 seconds
redis-cli ttl name	Get the remaining time for the key name
redis-cli del name	Delete the key name
redis-cli flush	Delete all keys
