type SyncNodeCollection interface {
	Load(ctx context.Context, logger log.Logger) ([]SyncNodeSetup, error)
	Check() error
}

type SyncNodeSetup 

type SyncNodeSetup interface {
	Setup(ctx context.Context, logger log.Logger) (SyncNode, error)
}

type SyncNodesController 

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

SyncNodesController manages a collection of active sync nodes. Sync nodes are used to sync the supervisor, and subject to the canonical chain view as followed by the supervisor.

func NewSyncNodesController 

func NewSyncNodesController(l log.Logger, depset depset.DependencySet, eventSys event.System, backend backend) *SyncNodesController

NewSyncNodesController creates a new SyncNodeController
