func Hash(data string) uint64

Types

type Bucket

type Bucket interface {
	//Store key value in bucket
	Set(kv store.KeyValue)

	//Returns key value from bucket. Return nil if key does not exist
	Get(key string) (store.KeyValue, bool)

	//Cleanup deletes all the expired key values
	Cleanup()

	//Save the entiries to file
	Save(path string) (string, error)

	//Load the entries from file
	Load(fileName string) (bool, error)
}

Bucket interface provides API to acess bucket

type Cache

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