Types ¶
type FileKeyValueStore ¶
type FileKeyValueStore struct {
// contains filtered or unexported fields
}
FileKeyValueStore stores each value into a separate file. KeySerializer maps a key to a unique file path (raletive to the store path) ValueSerializer and ValueDeserializer serializes/de-serializes a value to and from a byte array that is stored in the path derived from the key.
func New ¶
func New(opts *FileKeyValueStoreOptions) (*FileKeyValueStore, error)
New creates a new instance of FileKeyValueStore using provided options
func (*FileKeyValueStore) Delete ¶
func (fkvs *FileKeyValueStore) Delete(key interface{}) error
Delete deletes the value for a key.
func (*FileKeyValueStore) GetPath ¶
func (fkvs *FileKeyValueStore) GetPath() string
GetPath returns the store path
func (*FileKeyValueStore) Load ¶
func (fkvs *FileKeyValueStore) Load(key interface{}) (interface{}, error)
Load returns the value stored in the store for a key. If a value for the key was not found, returns (nil, ErrNotFound)
func (*FileKeyValueStore) Store ¶
func (fkvs *FileKeyValueStore) Store(key interface{}, value interface{}) error
Store sets the value for the key.
type FileKeyValueStoreOptions ¶
type FileKeyValueStoreOptions struct {
// Store path, mandatory
Path string
// Optional. If not provided, default key serializer is used.
KeySerializer KeySerializer
// Optional. If not provided, default Marshaller is used.
Marshaller Marshaller
// Optional. If not provided, default Unmarshaller is used.
Unmarshaller Unmarshaller
}
FileKeyValueStoreOptions allow overriding store defaults
type KeySerializer ¶
KeySerializer converts a key to a unique fila path
type Marshaller ¶
Marshaller marshals a value into a byte array
type Unmarshaller ¶
Unmarshaller unmarshals a value from a byte array
