func IsMetaBlob(blob []byte) (string, []byte, bool)

}

Meta holds the meta manager

func New

New initializes a meta manager

func (*Meta) Build

func (m *Meta) Build(data MetaData) (*blob.Blob, error)

Build convert the MetaData into a blo

func (*Meta) RegisterApplyFunc

func (m *Meta) RegisterApplyFunc(t string, f func(string, []byte) error)

RegisterApplyFunc registers a callback func for the given meta type

func (*Meta) Scan

func (m *Meta) Scan() error

Scan does nothing for the moment

type MetaData

type MetaData interface {
	Type() string
	Dump() ([]byte, error)
}

MetaData is the interface that must be implemented by the different meta data types
