	Name:        "persistent-memory",
	Constructor: Constructor,
}

Descriptor describes memory driver

Functions

func Constructor

func Constructor(prefix string, ctx unikv.DriverContextRaw) (unikv.Driver, error)

Constructor constructs new memory drivers

Types

type Driver

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

Driver is the memorydriver

func NewDriver

func NewDriver(prefix string, ctx *DriverContext) (*Driver, error)

NewDriver creates a driver

func (*Driver) Close

func (d *Driver) Close() error

Close closes driver

func (*Driver) Commit

func (d *Driver) Commit() error

Commit commits changes to file

func (*Driver) Get

func (d *Driver) Get(key string) (string, error)

Get gets data

func (*Driver) List

func (d *Driver) List() (interface{}, error)

List lists the keys

func (*Driver) Load

func (d *Driver) Load() error

Load loads data from file

func (*Driver) Put

func (d *Driver) Put(key string, value string) error

Put puts data

func (*Driver) Unset

Unset unsets data

type DriverContext

type DriverContext struct {
	Filename      string `json:"filename"`
	Filemode      int    `json:"filemode"`
	CommitWhenPut bool   `json:"commit_when_put"`
