Functions

func CopyContext

func CopyContext(ctx context.Context, dst io.Writer, src io.Reader) (int64, error)

func DeleteFile(path string) error

DeleteFile deletes files related to the provided id and param.

func ReadBuffer

func ReadBuffer(path string, buf *bytes.Buffer) (int64, error)

ReadBuffer read file to buffer
