# Ztimer

**Ztimer** is a Ruby gem that allows to get asynchronous delayed notifications. You can enqueue callbacks to be
called after some amount of time. 

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'ztimer'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install ztimer

## Usage

All you have to do is to tell **Ztimer** the delay after which your code have to be executed. An example of how to use it
is illustrated below:

```ruby
require 'ztimer'

delay = 5000 # milliseconds
Ztimer.after(delay) do
  puts "Doing something useful..."
end
```

By default **Ztimer** will run at maximum 20 notifications concurrently, so that if you have 100 notifications to be
executed at the same time, at maximum 20 of them will run at the same time. This is necessary in order to prevent uncontrolled
threads spawn when many notifications have to be sent at the same time.

Anyway, you can change the concurrency by calling `Ztimer.concurrency = <concurrency>`, where `<concurrency>` is the maximum number
of `Ztimer` workers allowed to run in parallel (ex: `Ztimer.concurrency = 50`).
