	// contains filtered or unexported fields
}

FileTransferer manages sending and receiving of files.

func New

func New(log *logger.Logger, streamer streamReadWriter, showProgress bool) *FileTransferer

New creates a new FileTransferer.

func (*FileTransferer) CanSend

func (s *FileTransferer) CanSend() bool

CanSend returns true if the file receive has finished. This is called to determine if a debugd instance can request files from this server.

func (*FileTransferer) GetFiles

func (s *FileTransferer) GetFiles() []FileStat

GetFiles returns the a copy of the list of files that have been received.

func (*FileTransferer) RecvFiles

func (s *FileTransferer) RecvFiles(stream RecvFilesStream) (err error)

RecvFiles receives files from the given stream.

func (*FileTransferer) SendFiles

func (s *FileTransferer) SendFiles(stream SendFilesStream) error

SendFiles sends files to the given stream.

func (*FileTransferer) SetFiles

func (s *FileTransferer) SetFiles(files []FileStat)

SetFiles sets the list of files that can be sent.

type RecvFilesStream

type RecvFilesStream interface {
	Recv() (*pb.FileTransferMessage, error)
}

RecvFilesStream is a stream that receives FileTransferMessages.

type SendFilesStream

type SendFilesStream interface {
	Send(*pb.FileTransferMessage) error
}

SendFilesStream is a stream that sends FileTransferMessages.
