# Dispatch [![Build Status](https://travis-ci.org/bmulvihill/dispatch.svg?branch=master)](https://travis-ci.org/bmulvihill/dispatch)

### In-memory job queuing

```crystal

# example.cr

require "./src/dispatch"

Dispatch.configure do |config|

  config.num_workers = 5

  config.queue_size = 10

  config.logger = Logger.new(IO::Memory.new)

end

class FakeJob

  include Dispatchable

  def perform(name)

    p "#{Time.now}: Hello, #{name}"

  end

end

class ErrorJob

  include Dispatchable

  def perform

    raise "Hello!"

  end

end

Dispatch.config # => 

FakeJob.dispatch("Bob")

FakeJob.dispatch("Emily")

FakeJob.dispatch_in(5.seconds, "Billy")

FakeJob.dispatch("Maddy")

ErrorJob.dispatch

Dispatch.successes # => 0

sleep 6

Dispatch.successes # => 4

Dispatch.failures # => 1

```

Output:

```

"2016-12-13 14:23:53 -0500: Hello, Bob"

"2016-12-13 14:23:53 -0500: Hello, Emily"

"2016-12-13 14:23:53 -0500: Hello, Maddy"

"2016-12-13 14:23:58 -0500: Hello, Billy"

```
