Types

type Asset

type Asset interface {
	// GetKey returns the key of this element
	GetKey() string
	// IsPublic returns whether or not this element gets stored in the public ledger
	IsPublic() bool
	// Encode returns a byte representation of the element which is the value that we store
	Encode() ([]byte, error)
	// Decode loads an Asset from a byte array and stores it to the provided interface
	Decode([]byte, interface{}) error
}

Asset is an interface for assets that get stored in either private collections or ledger

type PrivateAsset

type PrivateAsset interface {
	Asset
	// GetCollections returns the private collections to store the PrivateAsset to
	GetCollections() []string
}

PrivateAsset extends Asset and is used for assets that get stored in private collections

type PublicAsset

type PublicAsset interface {
	Asset
}

PublicAsset extends Asset and is used for assets that get stored in ledger
