win

Documentation

Overview

Package win is a test client. It implements the Shade drive.Client API, and silently succeeds any attempted operation. Read requests return nil for the value, as well as the error. You may configure it to appear as a Local client, or not.

Functions

func NewClient

func NewClient(c drive.Config) (drive.Client, error)

NewClient returns a client which will always win.

Types

type ChunkLister

type ChunkLister struct {
}

ChunkLister allows iterating the complete lack of chunks.

func (*ChunkLister) Err

func (c *ChunkLister) Err() error

Err returns precisely no errors.

func (*ChunkLister) Next

func (c *ChunkLister) Next() bool

Next always returns false, because there are no chunks.

func (*ChunkLister) Sha256

func (c *ChunkLister) Sha256() []byte

Sha256 returns nil. It should never be called, because there are no chunks.

type Drive

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

Drive is a test client implementation which silently succeeds every operation. If you provide an OAuthConfig.ClientID, Local will report false and Persistent will report true.

func (*Drive) GetChunk

func (s *Drive) GetChunk(sha256sum []byte, f *shade.File) ([]byte, error)

GetChunk returns no data, no error, every time.

func (*Drive) GetConfig

func (s *Drive) GetConfig() drive.Config

GetConfig returns an empty config.

func (*Drive) GetFile

func (s *Drive) GetFile(sha256sum []byte) ([]byte, error)

GetFile returns no data, no error, every time.

func (*Drive) ListFiles

func (s *Drive) ListFiles() ([][]byte, error)

ListFiles returns no data, no error, every time.

func (*Drive) Local

func (s *Drive) Local() bool

Local returns the value of Drive.Local.

func (*Drive) NewChunkLister

func (s *Drive) NewChunkLister() drive.ChunkLister

NewChunkLister returns an iterator which returns no chunks, no errors.

func (*Drive) Persistent

func (s *Drive) Persistent() bool

Persistent returns whether the storage is persistent across task restarts.

func (*Drive) PutChunk

func (s *Drive) PutChunk(sha256sum []byte, chunk []byte, f *shade.File) error

PutChunk returns success, every time.

func (*Drive) PutFile

func (s *Drive) PutFile(sha256sum, f []byte) error

PutFile returns success, every time.

func (*Drive) ReleaseChunk

func (s *Drive) ReleaseChunk(sha256sum []byte) error

ReleaseChunk returns success, every time.

func (*Drive) ReleaseFile

func (s *Drive) ReleaseFile(sha256sum []byte) error

ReleaseFile returns success, every time.

func (*Drive) Warm

func (s *Drive) Warm(chunks [][]byte, f *shade.File)

Warm is unnecessary for this client.
