Types

type KVMapStore

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

KVMapStore implements a non thread safe KVStore based on go maps

func NewKVMapStore

func NewKVMapStore() *KVMapStore

NewKVMapStore creates a KVMapStore

func (KVMapStore) Delete

func (kvms KVMapStore) Delete(key Key) error

Delete deletes the key from the map, or returns an error if the key is not found

func (*KVMapStore) Get

func (kvms *KVMapStore) Get(key Key) (Value, error)

Get returns the value associated with the key, or an error if the key does not exist

func (*KVMapStore) Set

func (kvms *KVMapStore) Set(key Key, value Value) error

Set adds or replaces the key / value pair in the map

type KVStore

type KVStore interface {
	// Set sets or replaces a key/value pair in the store
	Set(key Key, value Value) error

	// Get gets the value given the key
	Get(key Key) (Value, error)

	// Delete deletes a key, returns an error if the key don't exist
	Delete(key Key) error
}

KVStore is a simple interface for KeyValue stores

type Key

type Key []byte
