actor

Implementation Actor model in Go.

Design

Actor = {receive chan interface{}}

Usage

Install

go get github.com/dannypsnl/actor

Example

import (
    "github.com/dannypsnl/actor"
)

type Echo struct {
    actor.Actor
}

func (e *Echo) Fun() {
    msg := <-e.Receive
    switch msg.(type) {
    case strWithSender:
        m := msg.(strWithSender)
        m.sender <- m.str
        e.Fun()
    case closing:
        close(e.Receive)
    default:
        panic("Just don't want to resolve U!")
    }
}

type closing struct{}

type strWithSender struct {
    sender chan string
    str    string
}

func main() {
    echoPid := actor.Spawn(&Echo{}, []interface{}{})
    self := make(chan string)
    echoPid <- strWithSender{self, "Hi"}
    result := <-self
    println(result) // expected: Hi
    echoPid <- closing{}
}

Note

Erlang won't receive one message twice.

Documentation

Overview

actor pkg will help you have a best experience with Actor model programming

Index

• func Spawn(actor actorable, startArgs []interface{}) chan interface{}
• type Actor
  • func (a *Actor) Init()
  • func (a *Actor) Pid() chan interface{}

Functions

func Spawn

func Spawn(actor actorable, startArgs []interface{}) chan interface{}

Spawn help user start an actor like Erlang way. The Actor can execute in Spawn require method Fun & match interface Actorable

Types

type Actor

type Actor struct {
	Receive chan interface{}
}

Actor contains a receive channel help user don't need to understand how actor work at first. Just embedded Actor into their custom actor to use it

func (*Actor) Init

func (a *Actor) Init()

func (*Actor) Pid

func (a *Actor) Pid() chan interface{}

Pid return actor's pid
