Types

type Cache

type Cache interface {
	Get(namespace, key string) (value string, err error)
	Set(namespace, key, value string, ttl time.Duration) (err error)
	Delete(namespace, key string) (err error)
}

Cache describes an interface used to store generated data

func GetCacheByURI

func GetCacheByURI(uri string) (Cache, error)

GetCacheByURI instantiates a new Cache by the given URI string

type InMemCache

type InMemCache struct {
	// contains filtered or unexported fields
}

InMemCache implements the Cache interface for storage in memory

func NewInMemCache

func NewInMemCache() *InMemCache

NewInMemCache creates a new InMemCache

func (*InMemCache) Delete

func (i *InMemCache) Delete(namespace, key string) (err error)

Delete deletes data

func (*InMemCache) Get

func (i *InMemCache) Get(namespace, key string) (value string, err error)

Get retrieves stored data

func (*InMemCache) Set

func (i *InMemCache) Set(namespace, key, value string, ttl time.Duration) (err error)

Set stores data
