Types

type BeeMap

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

BeeMap is a map with lock

func NewBeeMap

func NewBeeMap() *BeeMap

NewBeeMap return new safemap

func (*BeeMap) Check

func (m *BeeMap) Check(k interface{}) bool

Check Returns true if k is exist in the map.

func (*BeeMap) Delete

func (m *BeeMap) Delete(k interface{})

Delete the given key and value.

func (*BeeMap) DeleteAll

func (m *BeeMap) DeleteAll()

DeleteAll DeleteAll

func (*BeeMap) Get

func (m *BeeMap) Get(k interface{}) interface{}

Get from maps return the k's value

func (*BeeMap) Items

func (m *BeeMap) Items() map[interface{}]interface{}

Items returns all items in safemap.

func (*BeeMap) Set

func (m *BeeMap) Set(k interface{}, v interface{}) bool

Set Maps the given key and value. Returns false if the key is already in the map and changes nothing.

type ID

type ID uint64

An ID is a unique, uniformly distributed 64-bit ID.

func GenerateID

func GenerateID() ID

GenerateID returns a randomly-generated 64-bit ID. This function is thread-safe. IDs are produced by consuming an AES-CTR-128 keystream in 64-bit chunks. The AES key is randomly generated on initialization, as is the counter's initial state. On machines with AES-NI support, ID generation takes ~30ns and generates no garbage.

func ParseID

func ParseID(s string) (ID, error)

ParseID parses the given string as a hexadecimal string.

func (ID) MarshalJSON

func (id ID) MarshalJSON() ([]byte, error)

MarshalJSON encodes the ID as a hex string.

func (ID) String

func (id ID) String() string

String returns the ID as a hex string.

func (*ID) UnmarshalJSON

func (id *ID) UnmarshalJSON(data []byte) error

UnmarshalJSON decodes the given data as either a hexadecimal string or JSON integer.

type Queue

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

Queue represents a single instance of the queue data structure.

func NewQueue

func NewQueue() *Queue

NewQueue New constructs and returns a new Queue.

func (*Queue) Add

func (q *Queue) Add(elem interface{})

Add puts an element on the end of the queue.

func (*Queue) Get

func (q *Queue) Get(i int) interface{}

Get returns the element at index i in the queue. If the index is invalid, the call will panic. This method accepts both positive and negative index values. Index 0 refers to the first element, and index -1 refers to the last.

func (*Queue) Length

func (q *Queue) Length() int

Length returns the number of elements currently stored in the queue.

func (*Queue) Peek

func (q *Queue) Peek() interface{}

Peek returns the element at the head of the queue. This call panics if the queue is empty.

func (*Queue) Remove

func (q *Queue) Remove() interface{}

Remove removes and returns the element from the front of the queue. If the queue is empty, the call will panic.
