func CreateNativeZeroLengthFiles

func CreateNativeZeroLengthFiles(info *metainfo.Info, dir string) (err error)

Creates natives files for any zero-length file entries in the info. This is a helper for file-based storages, which don't address or write to zero- length files because they have no corresponding pieces.

func NewFileWithCompletion

func NewFileWithCompletion(baseDir string, completion PieceCompletion) *fileClientImpl

func NewMMapWithCompletion

func NewMMapWithCompletion(baseDir string, completion PieceCompletion) *mmapClientImpl

func NewSqlitePieceCompletion

func NewSqlitePieceCompletion(dir string) (ret *sqlitePieceCompletion, err error)

type Client

type Client struct {
	// contains filtered or unexported fields

func NewClient

func NewClient(cl ClientImpl) *Client

func (Client) OpenTorrent

func (cl Client) OpenTorrent(info *metainfo.Info, infoHash metainfo.Hash) (*Torrent, error)

type ClientImpl

type ClientImpl interface {
	OpenTorrent(info *metainfo.Info, infoHash metainfo.Hash) (TorrentImpl, error)

Represents data storage for an unspecified torrent.

func NewFileByInfoHash

func NewFileByInfoHash(baseDir string) ClientImpl

File storage with data partitioned by infohash.

func NewFileWithCustomPathMaker

func NewFileWithCustomPathMaker(baseDir string, pathMaker func(baseDir string, info *metainfo.Info, infoHash metainfo.Hash) string) ClientImpl

Allows passing a function to determine the path for storing torrent data

type ClientImplCloser

type ClientImplCloser interface {
	Close() error

func NewBoltDB

func NewBoltDB(filePath string) ClientImplCloser

func NewFile

func NewFile(baseDir string) ClientImplCloser

All Torrent data stored in this baseDir

func NewMMap

func NewMMap(baseDir string) ClientImplCloser

func NewResourcePieces

func NewResourcePieces(p resource.Provider) ClientImplCloser

type Completion

type Completion struct {
	Complete bool
	Ok       bool

type Piece

type Piece struct {
	// contains filtered or unexported fields

func (Piece) ReadAt

func (p Piece) ReadAt(b []byte, off int64) (n int, err error)

func (Piece) WriteAt

func (p Piece) WriteAt(b []byte, off int64) (n int, err error)

type PieceCompletion

type PieceCompletion interface {
	Close() error

Implementations track the completion of pieces. It must be concurrent-safe.

func NewBoltPieceCompletion

func NewBoltPieceCompletion(dir string) (ret PieceCompletion, err error)

func NewMapPieceCompletion

func NewMapPieceCompletion() PieceCompletion

type PieceCompletionGetSetter

type PieceCompletionGetSetter interface {
	Get(metainfo.PieceKey) (Completion, error)
	Set(_ metainfo.PieceKey, complete bool) error

type PieceImpl

type PieceImpl interface {
	// These interfaces are not as strict as normally required. They can
	// assume that the parameters are appropriate for the dimensions of the
	// piece.
	// Called when the client believes the piece data will pass a hash check.
	// The storage can move or mark the piece data as read-only as it sees
	// fit.
	MarkComplete() error
	MarkNotComplete() error
	// Returns true if the piece is complete.
	Completion() Completion

Interacts with torrent piece data.

type Torrent

type Torrent struct {

func (Torrent) Piece

func (t Torrent) Piece(p metainfo.Piece) Piece

type TorrentImpl

type TorrentImpl interface {
	Piece(metainfo.Piece) PieceImpl
	Close() error
