SelectBySubnet implements selection from nodes with every subnet having equal probability.
func SelectBySubnetFromNodes ¶
func SelectBySubnetFromNodes(nodes []*Node) SelectBySubnet
SelectBySubnetFromNodes creates SelectBySubnet selector from nodes.
func (SelectBySubnet) Count ¶
func (subnets SelectBySubnet) Count() int
Count returns the number of maximum number of nodes that it can return.
type Selector ¶
type Selector interface { // Count returns the number of maximum number of nodes that it can return. Count() int // Select selects up-to n nodes and excluding the IDs. // When excludedNets is non-nil it will ensure that selected network is unique. Select(n int, excludedIDs []storj.NodeID, excludeNets map[string]struct{}) []*Node }
