Functions

func Hash

func Hash(data []byte) uint64

func Md5

func Md5(data []byte) []byte

func Md5Hex

func Md5Hex(data []byte) string

Types

type ConsistentHash

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

func NewConsistentHash

func NewConsistentHash() *ConsistentHash

func NewCustomConsistentHash

func NewCustomConsistentHash(replicas int, fn HashFunc) *ConsistentHash

func (*ConsistentHash) Add

func (h *ConsistentHash) Add(node interface{})

Add adds the node with the number of h.replicas, the later call will overwrite the replicas of the former calls.

func (*ConsistentHash) AddWithReplicas

func (h *ConsistentHash) AddWithReplicas(node interface{}, replicas int)

AddWithReplicas adds the node with the number of replicas, replicas will be truncated to h.replicas if it's larger than h.replicas, the later call will overwrite the replicas of the former calls.

func (*ConsistentHash) AddWithWeight

func (h *ConsistentHash) AddWithWeight(node interface{}, weight int)

AddWithWeight adds the node with weight, the weight can be 1 to 100, indicates the percent, the later call will overwrite the replicas of the former calls.

func (*ConsistentHash) Get

func (h *ConsistentHash) Get(v interface{}) (interface{}, bool)

func (*ConsistentHash) Remove

func (h *ConsistentHash) Remove(node interface{})

type HashFunc

type HashFunc func(data []byte) uint64
