Types

type Cache

type Cache interface {
	// CreateNamespace creates a new bucket in cache.
	CreateNamespace(namespace string)

	// Put writes a key-value pair. If the namespace is not found, create one.
	Put(namespace string, key, value interface{}) error

	// Get returns the value, or 'ErrKeyNotFound'. If the namespace is not found, returns 'ErrNamespaceNotFound'.
	Get(namespace string, key interface{}) (interface{}, error)
}
