Package retigo provides typed Redis commands that can be used with (generalized) redigo connections. Each Redis command has a redigo Do and Send version.
The provided functions return structures representing Redis command return
types. These retigo types are essentially thin wrappers around
redigo command responses. Their Result methods return the appropriate
Go types as per the redigo Redis to Go type conversion specifications.
For example, BulkString.Result returns ([]byte, error)
Suppose a conn is a redigo redis.Conn instance connected to some Redis
instance that stores the value "value1" in the key "key1".
var value []byte
value, err := retigo.Get(conn, "key1").Result() // string(value) == "value1" is true
// is equivalent to
value, err := redis.Bytes(conn.Do("GET", "key1")) The original redigo response is returned by the retigo type's Redigo method,
as follows:
val, err := retigo.Get(conn, "key1")
// is equivalent to
val, err := conn.Do("GET", "key1")All retigo types (the values returned by the package's functions) have
methods mirroring the basic redigo type assertion helper functions. The
Array type has access to the array response specific helper functions.
Moreover, since retigo return values respect the Redis to Go type conversions present
in redigo, redigo's type assertion helper functions can be chained with
retigo types. For example,
i, err := retigo.Get(conn, "key").Int()
// is equivalent to
i, err := redis.Int(retigo.Get(conn, "key").Redigo())
// is equivalent to
i, err := redis.Int(conn.Do("GET", "key"))
