Usage:
m := partmap.NewPartitionedMapWithDefaultPartitioner(3) // 3 partitions
m.Set("key", 123)
value, err := m.Get("key")
if err != nil && !errors.Is(err, partmap.ErrNotFound) {
panic(err)
}
println(value) // 123
if err := m.Del("key"); err != nil {
panic(err)
}

PartitionedMap is a map that is partitioned into several maps.
func NewPartitionedMap ¶
func NewPartitionedMap(partitioner partitioner, partsnum uint) *PartitionedMap
NewPartitionedMap creates new partitioned map with given partitioner and number of partitions.
func NewPartitionedMapWithDefaultPartitioner ¶
func NewPartitionedMapWithDefaultPartitioner(partsnum uint) *PartitionedMap
NewPartitionedMapWithDefaultPartitioner creates new partitioned map with default partitioner and given number of partitions.
func (*PartitionedMap) Del ¶
func (c *PartitionedMap) Del(key string) error
Del deletes value for given key.
