Types

type FileHandler

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

FileHandler contains all the core file operations logic It can be used directly with any BlockStore implementation

func NewFileHandler

func NewFileHandler(bs fileblockstore.BlockStore) *FileHandler

NewFileHandler creates a new FileHandler with the given BlockStore

func (*FileHandler) AddFile

func (fh *FileHandler) AddFile(ctx context.Context, r io.Reader) (ipld.Node, error)

AddFile adds file to ipfs storage

func (*FileHandler) DAGService

func (fh *FileHandler) DAGService() ipld.DAGService

DAGService returns the underlying DAG service

func (*FileHandler) GetFile

func (fh *FileHandler) GetFile(ctx context.Context, c cid.Cid) (ufsio.ReadSeekCloser, error)

GetFile gets file from ipfs storage

func (*FileHandler) HasCid

func (fh *FileHandler) HasCid(ctx context.Context, c cid.Cid) (exists bool, err error)

HasCid checks if CID exists

type FileService

type FileService interface {
	// GetFile gets file from ipfs storage
	GetFile(ctx context.Context, c cid.Cid) (ufsio.ReadSeekCloser, error)
	// AddFile adds file to ipfs storage
	AddFile(ctx context.Context, r io.Reader) (ipld.Node, error)
	// DAGService returns ipld.DAGService object
	DAGService() ipld.DAGService
	// HasCid checks is CID exists
	HasCid(ctx context.Context, c cid.Cid) (exists bool, err error)
	app.Component
}

func New

func New() FileService
