Types

type Evaluator

type Evaluator interface {
	// EvaluateParents sort parents by evaluating multiple feature scores.
	EvaluateParents(parents []*resource.Peer, child *resource.Peer, taskPieceCount int32) []*resource.Peer

	// IsBadNode determine if peer is a failed node.
	IsBadNode(peer *resource.Peer) bool
}

Evaluator is an interface that evaluates the parents.
