Variables

var ErrNotFound = errors.New("network map not found")

ErrNotFound is the error returned when network map was not found in storage.

Functions

func GetLatestNetworkMap

func GetLatestNetworkMap(src Source) (*netmap.Netmap, error)

GetLatestNetworkMap requests and returns latest network map from storage.

func GetPreviousNetworkMap

func GetPreviousNetworkMap(src Source) (*netmap.Netmap, error)

GetPreviousNetworkMap requests and returns previous from latest network map from storage.

Types

type Source

type Source interface {
	// GetNetMap reads the diff-th past network map from the storage.
	// Calling with zero diff returns latest network map.
	// It returns the pointer to requested network map and any error encountered.
	//
	// GetNetMap must return exactly one non-nil value.
	// GetNetMap must return ErrNotFound if the network map is not in storage.
	//
	// Implementations must not retain the network map pointer and modify
	// the network map through it.
	GetNetMap(diff uint64) (*netmap.Netmap, error)
}

Source is an interface that wraps basic network map receiving method.

type State

type State interface {
	// CurrentEpoch returns number of current NeoFS epoch.
	CurrentEpoch() uint64
}

State groups current system state parameters.
