Ione

If you're reading this on GitHub, please note that this is the readme for the development version and that some features described here might not yet have been released. You can find the readme for a specific version either through rubydoc.info or via the release tags (here is an example).

Ione is a framework for reactive programming in Ruby. It is based on the reactive core of cql-rb, the Ruby driver for Cassandra.

Features

Futures & promises

At the core of Ione is a futures API. Futures make it easy to compose asynchronous operations.

Evented IO

A key piece of the framework is an IO reactor with which you can easily build network clients and servers.

Byte buffer

Networking usually means pushing lots of bytes around and in Ruby it's easy to make the mistake of using strings as buffers. Ione provides an efficient byte buffer implementation as an alternative.

Examples

The examples directory has some examples of what you can do with Ione, for example:

• redis_client is a more or less full featured Redis client that uses most of Ione's features.
• http_client is a simplistic HTTP client that uses Ione and http_parser.rb to make HTTP GET request. It also shows how to make TLS connections.
• cql-rb is a high performance Cassandra driver and where Ione was originally developed.
• cassandra-driver is the successor to cql-rb.
• ione-rpc is a RPC framework built on Ione. It makes it reasonably easy to build networked applications without having to reinvent the wheel.
