var (
	GroupIDShards       = map[nodeconfig.ShardID]nodeconfig.GroupID{}

)

GroupIDShards is a map of ShardGroupID ID key is the shard ID value is the corresponding group ID

Types

type Manager

type Manager struct {
	// contains filtered or unexported fields
}

Manager stores all services for service manager.

func NewManager

func NewManager() *Manager

func (*Manager) StopServices

type NodeConfig

type NodeConfig struct {
	// The three groupID design, please refer to https://github.com/harmony-one/harmony/blob/master/node/node.md#libp2p-integration
	Beacon       nodeconfig.GroupID                           // the beacon group ID
	ShardGroupID nodeconfig.GroupID                           // the group ID of the shard
	Client       nodeconfig.GroupID                           // the client group ID of the shard
	IsBeacon     bool                                         // whether this node is a beacon node or not
	ShardID      uint32                                       // shardID of this node
	Actions      map[nodeconfig.GroupID]nodeconfig.ActionType // actions on the groups
}

NodeConfig defines a structure of node configuration that can be used in services. This is to pass node configuration to services and prvent cyclic imports

type Service

type Service interface {
	Start() error
	Stop() error
	APIs() []rpc.API // the list of RPC descriptors the service provides
}

Service is the collection of functions any service needs to implement.
