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 AnnouncedKeys

type AnnouncedKeys interface {
	// Checks if key was announced by local node.
	IsLocalKey(key []byte) bool
}

AnnouncedKeys is an interface of utility for working with announced public keys of the storage nodes.

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)

	// GetNetMapByEpoch reads network map by the epoch number from the storage.
	// It returns the pointer to requested network map and any error encountered.
	//
	// Must return exactly one non-nil value.
	//
	// Implementations must not retain the network map pointer and modify
	// the network map through it.
	GetNetMapByEpoch(epoch uint64) (*netmap.Netmap, error)

	// Epoch reads current epoch from the storage.
	// It returns number of the current epoch and any error encountered.
	//
	// Must return exactly one non-default value.
	Epoch() (uint64, 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.
