Functions

func Debug

func Debug(debug bool)

Debug toggles debug mode

Types

type Chunk

type Chunk struct {
	Bytes    []byte `json:"b,omitempty"`
	Location int64  `json:"l,omitempty"`
}

Chunk contains information about the needed bytes

type Client

type Client struct {
	Options                         Options
	Pake                            *pake.Pake
	Key                             []byte
	ExternalIP, ExternalIPConnected string

	// steps involved in forming relationship
	Step1ChannelSecured       bool
	Step2FileInfoTransfered   bool
	Step3RecipientRequestFile bool
	Step4FileTransfer         bool
	Step5CloseChannels        bool
	SuccessfulTransfer        bool

	// send / receive information of all files
	FilesToTransfer           []FileInfo
	FilesToTransferCurrentNum int
	FilesHasFinished          map[int]struct{}

	// send / receive information of current file
	CurrentFile            *os.File
	CurrentFileChunkRanges []int64
	CurrentFileChunks      []int64

	TotalSent             int64
	TotalChunksTransfered int
	// contains filtered or unexported fields
}

Client holds the state of the croc transfer

func New

func New(ops Options) (c *Client, err error)

New establishes a new connection for transferring files between two instances.

func (*Client) Receive

func (c *Client) Receive() (err error)

Receive will receive a file

func (*Client) Send

func (c *Client) Send(options TransferOptions) (err error)

Send will send the specified file

type FileInfo

type FileInfo struct {
	Name         string    `json:"n,omitempty"`
	FolderRemote string    `json:"fr,omitempty"`
	FolderSource string    `json:"fs,omitempty"`

	Ask            bool
}

Options specifies user specific options

type RemoteFileRequest

type RemoteFileRequest struct {
	CurrentFileChunkRanges    []int64
	FilesToTransferCurrentNum int
	MachineID                 string
}

RemoteFileRequest requests specific bytes

type SenderInfo

type SenderInfo struct {
	FilesToTransfer []FileInfo
	MachineID       string
	Ask             bool
}

SenderInfo lists the files to be transferred
