Types

type Entry

type Entry interface {
	// Reference returns the address of the file.
	Reference() swarm.Address
	// Metadata returns the metadata of the file.
	Metadata() map[string]string
}

Entry represents a single manifest entry.

func NewEntry

func NewEntry(reference swarm.Address, metadata map[string]string) Entry

NewEntry creates a new manifest entry.

type Interface

type Interface interface {
	// Type returns manifest implementation type information
	Type() string
	// Add a manifest entry to the specified path.
	Add(context.Context, string, Entry) error
	// Remove a manifest entry on the specified path.
	Remove(context.Context, string) error
	// Lookup returns a manifest entry if one is found in the specified path.
	Lookup(context.Context, string) (Entry, error)
	// HasPrefix tests whether the specified prefix path exists.
	HasPrefix(context.Context, string) (bool, error)
	// Store stores the manifest, returning the resulting address.
	Store(context.Context, ...StoreSizeFunc) (swarm.Address, error)
	// IterateAddresses is used to iterate over chunks addresses for
	// the manifest.
	IterateAddresses(context.Context, swarm.AddressIterFunc) error
}
