rs-ipfix

This is a library to parse IPFIX/Netflow v10 (RFC7011) data with functionality to export it as JSON.

An example app using this library to send data to Elasticsearch is available at https://gitlab.com/dominotree/ipfix-elasticsearch

There is a fair bit of cleanup and optimization that needs to be done here, but it should currently be fully functional and capable of processing a large number of flows.
