Types

type Client

type Client struct {
	TTL time.Duration
	// contains filtered or unexported fields
}

Client is the entrypoint into Redis

func NewClient

func NewClient(address, password string, db int) (*Client, error)

NewClient returns a configured Client instance, verifying a successful connection to redis

func NewClientFrom

func NewClientFrom(address string) (*Client, error)

NewClientFrom returns a configured Client instance from a redis address, verifying a successful connection to redis

func (*Client) Close

func (client *Client) Close() error

Close closes a redis client

func (*Client) CompareAndSwap

func (client *Client) CompareAndSwap(ctx context.Context, key storage.Key, oldValue, newValue storage.Value) (err error)

CompareAndSwap atomically compares and swaps oldValue with newValue

func (*Client) Delete

func (client *Client) Delete(ctx context.Context, key storage.Key) (err error)

Delete deletes a key/value pair from redis, for a given the key

func (*Client) FlushDB

func (client *Client) FlushDB() error

FlushDB deletes all keys in the currently selected DB.

func (*Client) Get

func (client *Client) Get(ctx context.Context, key storage.Key) (_ storage.Value, err error)

Get looks up the provided key from redis returning either an error or the result.

func (*Client) GetAll

func (client *Client) GetAll(ctx context.Context, keys storage.Keys) (_ storage.Values, err error)

GetAll is the bulk method for gets from the redis data store. The maximum keys returned will be storage.LookupLimit. If more than that is requested, an error will be returned

func (*Client) Iterate

func (client *Client) Iterate(ctx context.Context, opts storage.IterateOptions, fn func(context.Context, storage.Iterator) error) (err error)

Iterate iterates over items based on opts

func (*Client) List

func (client *Client) List(ctx context.Context, first storage.Key, limit int) (_ storage.Keys, err error)

List returns either a list of keys for which boltdb has values or an error.

func (*Client) Put

func (client *Client) Put(ctx context.Context, key storage.Key, value storage.Value) (err error)

Put adds a value to the provided key in redis, returning an error on failure.
