# Async::Pool

Provides support for connection pooling both singleplex and multiplex resources.

[![Build Status](https://travis-ci.com/socketry/async-pool.svg)](https://travis-ci.com/socketry/async-pool)

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'async-pool'
```

And then execute:

	$ bundle

Or install it yourself as:

	$ gem install async-pool

## Usage

`Async::Pool::Controller` provides support for both singleplex (one stream at a time) and multiplex resources (multiple streams at a time).

`Async::Pool::Resource` is provided as an interface and to document how to use the pools. However, you wouldn't need to use this in practice and just implement the appropriate interface on your own objects.

```ruby
pool = Async::Pool::Controller.new(Async::Pool::Resource)

pool.acquire do |resource|
	# resource is implicitly released when exiting the block.
end

resource = pool.acquire

# Return the resource back to the pool:
pool.release(resource)
```
