Handles incoming byte messages from Redis and decodes them according to the Redis Serialization Protocol (RESP).

See NIO.ByteToMessageDecoder, RESPTranslator and https://redis.io/topics/protocol

An object that operates in a First In, First Out (FIFO) request-response cycle.

RedisCommandHandler is a NIO.ChannelDuplexHandler that sends RedisCommand instances to Redis, and fulfills the command’s NIO.EventLoopPromise as soon as a RESPValue response has been received from Redis.

Encodes outgoing RESPValue data into a raw ByteBuffer according to the Redis Serialization Protocol (RESP).

See NIO.MessageToByteEncoder, RESPTranslator, and https://redis.io/topics/protocol

A concrete RedisClient implementation that represents an individual connection to a Redis database instance.

For basic setups, you will just need a NIO.SocketAddress and a NIO.EventLoop and perhaps a password.

let eventLoop: EventLoop = ...
let connection = RedisConnection.connect(
    to: try .makeAddressResolvingHost("my.redis.url", port: RedisConnection.defaultPort),
    on: eventLoop
).wait()

let result = try connection.set("my_key", to: "some value")
    .flatMap { return connection.get("my_key") }
    .wait()

print(result) // Optional("some value")

Note: wait() is used in the example for simplicity. Never call wait() on an event loop.

See NIO.SocketAddress, NIO.EventLoop, and RedisClient

A specialized wrapper class for working with Metrics.Gauge objects for the purpose of an incrementing or decrementing count of active Redis connections.
