Functions

func InitializeContext 

func InitializeContext(ctx context.Context) context.Context

InitializeContext adds the redis session to the context. The new context is returned because context is immutable.

	RedisClientService ClientFunctions
	// contains filtered or unexported fields
}

Session contains the information of a redis session.

	key string,
	props map[string]interface{},
) error

func (s *Session) ValidateJSONValue(
	ctx context.Context,
	key string,
	props map[string]interface{},
) error

func (s *Session) ValidateNonExistantKey(ctx context.Context, key string) error

ValidateNonExistantKey checks if the redis key has not value.

func (*Session) ValidateTextValue 

func (s *Session) ValidateTextValue(ctx context.Context, key, expectedValue string) error

ValidateTextValue checks if the text value for a redis key equals the expected value. It uses session TTL to establish an expiration time (no expiration if TTL is 0).

func (s *Session) WaitForJSONMessageWithProperties(
	ctx context.Context,
	timeout time.Duration,
	props map[string]interface{},
) error
