Types

type Client

type Client struct {
	*redis.Client
}

Client represents a connection with a Redis client.

func New

func New(opt Options) *Client

New returns a new Redis client.

func (*Client) Close

func (c *Client) Close(ctx context.Context, args ...interface{}) error

Close closes the connection to the underlying Redis client.

func (*Client) Do

func (c *Client) Do(ctx context.Context, args ...interface{}) *redis.Cmd

Do creates and processes a custom Cmd on the underlying Redis client.

func (*Client) Ping

func (c *Client) Ping(ctx context.Context) *redis.StatusCmd

Ping contacts the redis client, and returns 'PONG' if the client is reachable. It can be used to test whether a connection is still alive, or measure latency.

type Options

type Options redis.Options

Options wraps redis.Options for easier usage.
