Types

type LogInterface

type LogInterface struct {
	Prod *zap.Logger
	Dev  *zap.Logger
}

LogInterface inherited by internal packages to provide hierarchical logs

type Once

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

Once is an object that will perform exactly one action.

func (*Once) Do

func (o *Once) Do(f func()) bool

Do calls the function f if and only if Do is being called for the first time for this instance of Once. In other words, given

var once Once

if once.Do(f) is called multiple times, only the first call will invoke f, even if f has a different value in each invocation. A new instance of Once is required for each function to execute.

Do is intended for initialization that must be run exactly once. Since f is niladic, it may be necessary to use a function literal to capture the arguments to a function to be invoked by Do:

config.once.Do(func() { config.init(filename) })

Because no call to Do returns until the one call to f returns, if f causes Do to be called, it will deadlock.

If f panics, Do considers it to have returned; future calls of Do return without calling f.

type OnceWait

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

OnceWait is an object that will perform exactly one action.

func (*OnceWait) Do

func (o *OnceWait) Do(f func()) bool

Do calls the function f if and only if Do is being called for the first time for this instance of Once. In other words, given

var once Once

if once.Do(f) is called multiple times, only the first call will invoke f, even if f has a different value in each invocation. A new instance of Once is required for each function to execute.

Do is intended for initialization that must be run exactly once. Since f is niladic, it may be necessary to use a function literal to capture the arguments to a function to be invoked by Do:

config.once.Do(func() { config.init(filename) })

Because no call to Do returns until the one call to f returns, if f causes Do to be called, it will deadlock.

If f panics, Do considers it to have returned; future calls of Do return without calling f.

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 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.

type RetainObject

type RetainObject interface {
	Topic() string
}

RetainObject general interface of the retain as not only publish message can be retained

type TopicMessenger

type TopicMessenger interface {
	Publish(interface{}) error
	Retain(RetainObject) error
}

TopicMessenger interface for session or systree used to publish or retain messages
