An example of using the Redis APPEND command is: -// -// n, err := conn.Do("APPEND", "key", "value") -// -// The Do method converts command arguments to binary strings for transmission -// to the server as follows: -// -// Go Type Conversion -// []byte Sent as is -// string Sent as is -// int, int64 strconv.FormatInt(v) -// float64 strconv.FormatFloat(v, 'g', -1, 64) -// bool true -> "1", false -> "0" -// nil "" -// all other types fmt.Print(v) -// -// Redis command reply types are represented using the following Go types: -// -// Redis type Go type -// error redis.Error -// integer int64 -// simple string string -// bulk string []byte or nil if value not present. -// array []interface{} or nil if value not present. -// -// Use type assertions or the reply helper functions to convert from -// interface{} to the specific Go type for the command result. -// -// Pipelining -// -// Connections support pipelining using the Send, Flush and Receive methods. -// -// Send(commandName string, args ...interface{}) error -// Flush() error -// Receive() (reply interface{}, err error) -// -// Send writes the command to the connection's output buffer.

Connections do -// allow a concurrent reader and writer. -// -// Because the Do method combines the functionality of Send, Flush and Receive, -// the Do method cannot be called concurrently with the other methods. -// -// For full concurrent access to Redis, use the thread-safe Pool to get and -// release connections from within a goroutine. -// -// Publish and Subscribe -// -// Use the Send, Flush and Receive methods to implement Pub/Sub subscribers. -// -// c.Send("SUBSCRIBE", "example") -// c.Flush() -// for { -// reply, err := c.Receive() -// if err != nil { -// return err -// } -// // process pushed message -// } -// -// The PubSubConn type wraps a Conn with convenience methods for implementing -// subscribers. The Subscribe, PSubscribe, Unsubscribe and PUnsubscribe methods -// send and flush a subscription management command. The receive method -// converts a pushed message to convenient types for use in a type switch. -// -// psc := redis.PubSubConn{c} -// psc.Subscribe("example") -// for { -// switch v := psc.Receive().(type) { -// case redis.Message: -// fmt.Printf("%s: message: %s\n", v.Channel, v.Data) -// case redis.Subscription: -// fmt.Printf("%s: %s %d\n", v.Channel, v.Kind, v.Count) -// case error: -// return v -// } -// } -// -// Reply Helpers -// -// The Bool, Int, Bytes, String, Strings and Values functions convert a reply -// to a value of a specific type. To allow convenient wrapping of calls to the -// connection Do and Receive methods, the functions take a second argument of -// type error.
